? Shortcut: WP:DINOART Dinosaur Image Review Archives Current Image Review Page Gallery of approved images Requested Image List ? This page is mainly for reviewing the accuracy of dinosaur life restorations (usually by the artists themselves, but anyone who wants an image scrutinized is welcome to post it for review). Any other image, such as size comparisons or photos of skeletal mounts, can also be posted here to review their accuracy. If you want to submit dinosaur images for accuracy review, place them here as well as links to what you used as references. If you want to participate as reviewer, you can put the page on your watchlist. New images of any type can also be requested by including "Request:" in the section title; if submitted, such an image will thereafter be reviewed here. Sections are archived automatically after some time when a discussion stalls, to encourage speedy responses from both artists and reviewers. It is allowed to revive sections if they have been archived before being resolved, unlike regular talk page archives. Modifications of previously uploaded amateur restorations to correct anatomical inaccuracies is encouraged (including by others than the original artists), but modifications of historical restorations are discouraged, as these should be used to show historical ideas. Modifications to restorations published in peer-reviewed journals should be uploaded as separate files, so that both versions are available. Images that have been deemed inaccurate should be tagged with the Wikimedia Commons template "Inaccurate paleoart" c:Template:Inaccurate paleoart (which automatically adds the "Inaccurate paleoart" category (c:Category:Inaccurate paleoart), so they can be prevented from being used and easily located for correction. User created images are not considered original research, per WP:OI and WP:PERTINENCE, but it is appreciated if sources used are listed in file descriptions (this is often requested during WP:Featured Article reviews). For reviews of non-dinosaur paleoart, see WikiProject Palaeontology's paleoart review page: Criteria sufficient for using an image: See Dinosaurs/Image review/To Do List#Guidelines for dinosaur restorations Guidelines for dinosaur restorations for minimum requirements for anatomical accuracy in dinosaur restorations used in articles. If an image is included for historical value, the image caption should explain that it is an outdated reconstruction. Images of historical interest should not be used in the taxobox or paleobox, but preferably in a section of the text discussing the history of a taxon. Criteria for removing an image: Images should not speculate unnecessarily beyond what has been indicated by reliable sources. Therefore, depicting overly speculative physical features, behaviors, and pathologies should be avoided, to prevent WP:OR issues. Restorations that show serious pathologies known from fossil evidence are welcome, but should not be used as the main representation of a given taxon. These should instead show healthy, typical individuals, and not focus on unknown areas of their anatomy. Since Wikipedia is an encyclopaedia rather than an art gallery, it is not the place for artistic experimentation, and we cannot include every piece of available artwork. Image differs appreciably from known skeletal elements. Example: A Deinonychus reconstructed with four fingers. Image differs appreciably from implied skeletal elements (via phylogenetic bracketing). Example: An oviraptorid known only from postcranial elements reconstructed with teeth, a feature made highly improbable by its phylogenetic position. Image differs appreciably from known non-skeletal elements. Example: An image of Microraptor lacking primary feathers. Image differs appreciably from implied non-skeletal elements. Example: A Nomingia depicted without feathers, since a skeletal feature (the pygostyle) and phylogenetic bracketing (more advanced than Caudipteryx) imply that it was feathered. Example: A Ceratosaurus depicted with advanced feathers, since a skeletal feature (osteoderms) and its proximity to Carnotaurus (extensive scale impressions) imply that it lacked advanced feathers. The discovery of Kulindadromeus and integument in exceptionally preserved heterodontosaurids provides evidence for some form of filamentous integument being the plesiomorphic condition in Ornithischia. As loss of filamentous integument is well known in many dinosaur clades, skin impressions and thermodynamic considerations should be given priority over phylogenetic bracketing. Image pose differs appreciably from known range of motion. Example: Theropod dinosaurs reconstructed with overly flexed tails or pronated "bunny-style" hands. Exception: If the range of motion is debated in the scientific literature, as is the case with sauropod neck position. Image differs appreciably from known size estimates. Example: An image of an adult Torvosaurus which shows it being as large as an adult Apatosaurus. Exception: If the size of the animal is contested or the individual in question is a gigantism-inflicted individual. Image differs appreciably from known physiological constraints. Example: An image of a dinosaur urinating, giving birth to live young, or making vocal sounds with its jaw, all made unlikely by phylogenetic position and physical constraints (archosaurs less basal then songbirds likely could not vocalize too much, if at all). Image seems heavily inspired by another piece of media or directly copied from it. Example: A image of Tyrannosaurus or Velociraptor depicting them as they appear in Jurassic Park being used in the articles on the genera, or an illustration of Deinonychus being a direct trace of another illustration of the same genus. Image depicts a scene which is anachronistic or contradicts known geographic range. Example: Megalosaurus bucklandii chasing an Nanosaurus agilis, two animals which did not live together. Example: Dinosaurs from the Triassic or Jurassic depicted walking on grass, which did not exist at that time. Exception: Photographs of life-sized models taken in parks. It should be made clear in the caption that these are models. Approved images: Images that have been approved by the Wikipedia:WikiProject Dinosaurs team can now be found at Category:Approved dinosaur images. Images that have been deemed inaccurate should be placed in the Wikimedia Commons category "Inaccurate dinosaur restorations" c:Category:Inaccurate dinosaur restorations, so they can be easily located for correction.

Hello, I'm back here, I was updating my drawings and scanning them for the last month after a resurgence of my passion for editing Wikipedia, uploading drawings, photographs and categorizing on Commons (I must thank the paleoartists Ventura Salas and Joschua Knüppe for my total reactivation of the passion for paleoart). The pandemic and quarantine hit me very hard (I think like everyone else) and I was very depressed for the last 4 years. Anyway, I'm back home (here), and I discovered that the Wikiproyect is more active on paleoart and images since I became inactive, good to see that, forgive me if I didn't respond to the times some of you tagged me. Now I'll read most of the archives from 2021 to present, I've read a few of them, and I'm not going to lie when I say that when I read Miracusaurs' comment about the Tlatolophus drawing in Archive 5 I laughed for a whole minute, you made my day, thank you! Well, I will ask you to please review some of the latest updates of the drawings and other new ones that I made. Any comments, advice or constructive criticism is welcome, thanks in advance! --Levi bernardo (talk) 11:21, 15 March 2024 (UTC)

I've also been working on an illustration of Banji, I saw that a miniature Banji illustration by Matt Martyniuk from a plate was cropped, extracted and enhanced with AI by a Russian biologist, the illustration changed a little with it, but It looks decent, maybe we could ask Matt for the original file or something to improve that image even more,I am trying to learn more about Oviraptosaurs to review the facial, mandibular and keratin details to give more coherence and improvement to my current illustration and perhaps the old ones of Huanansaurus and Hagryphus.

I was also working on editions and anatomical arrangements for Lepidus, I couldn't believe that I had the physical update done for 4 years and that the drawing is almost a decade old and that I had not yet edited it since 2015. I haven't finished editing the head and hands yet, the right leg needs a slight shortening. Levi bernardo (talk) 13:01, 15 March 2024 (UTC)

Given how fragmentary Lepidus is, any Lepidus illustration will be heavily based on more complete ancestral theropods such as Coelophysis or Megapnosaurus, but based on those the neck is proportionally way too thick. These animals had both slender bodies and slender necks. As for Banji, could you clarify what you mean by "enhanced with AI"? At the very least this seems like it is based on Matt Martyniuk's copyrighted work, and would not be clear-cut case of Fair Use so it is not suitable for Wikipedia in this form. Skye McDavid (talk) 13:35, 15 March 2024 (UTC)

In fact it was updated following the anatomy of Coelophysis and the skull of Megapnosaurus. I had already thinned the neck by 25%, I will try to review in more detail how thinner the neck can be, but also perhaps one reason why it looks so thick is that it has some filaments that increase its apparent thickness. Thank you!

Banji By Matt

The specific image I am referring to that is here in Commons, you can look at the version history and you will notice the changes between the first version and the updated one and you will notice the changes made, it would be necessary to analyze whether or not it is really improved with AI . That's why I mentioned that image, to know what to do in these cases and review its cranial anatomy. Levi bernardo (talk) 18:49, 15 March 2024 (UTC)

According to the metadata of the image, it was apparently retouched with Paint.NET, so I may have been wrong in relating it to an AI alteration Levi bernardo (talk) 18:59, 15 March 2024 (UTC)

Regarding filaments on Lepidus, I see no reason to put a thick layer of filaments on the neck and a much thinner one one the body itself. Coelphysoids largely have similar proportions, so Scott Hartman's Coelophysis skeletal is a good reference. Note that many reconstructions based on older skeletal reconstructions have the gastralia too high, with insufficient dorsoventral space for internal organs. As for the retouched image, it can only be used on Wikipedia if both the original work and the modified version are freely licensed. The original version (Matt's) is freely licensed but I don't know about the one retouched by the "Russian biologist". It would have to be published under a Wikipedia-compatible license to be used here. The illustration you have linked seems to be a life reconstruction digitally layered below the skull diagram already used in the article. No copyright status on DeviantArt, and in my opinion wouldn't add value to the article. Skye McDavid (talk) 21:50, 15 March 2024 (UTC)

Ok, I will keep Lepidus comments in mind, in fact I was editing the portion of the area that goes from gastralia to pubis, but I certainly omitted that detail, thank you, I had only enlarged the pubic section and ignored the gastralia portion. As for the filaments, I will see how to solve it and give it a better appearance. --Levi bernardo (talk)

March 27 revision of Lepidus looks nice. Skye McDavid (talk) 19:54, 28 March 2024 (UTC)

Excellent, thanks. I will continue to gradually modify more details step by step. Thanks for the help. Levi bernardo (talk) 06:31, 2 April 2024 (UTC)

As for Banji:, I think I've already created a confusion. I mean that my image is my complete authorship in the artistic aspect and based directly on the skull diagram in Xu & Han 2010, (and I want to upload it to Commons, but first review it here). I leave a video of the SpeedPaint as proof. I suppose that by wanting to mention the other illustration I generated this confusion. What I wanted to know was if we could use the illustration or renew it, and if necessary ask Matt to update it, I recently saw him on Facebook mentioning an illustration of his that was published in a newspaper and I thought maybe we could ask him for an image of that work of yours in better resolution. Excuse my errors, I am not a native English speaker and even though I know how to speak it more than the last time I was here, I still cannot apply the exact terms and in the proper grammatical order. Levi bernardo (talk) 00:22, 16 March 2024 (UTC)

I improved Banji's illustration, I corrected the mouth area and found the appropriate way to reconstruct it, and also increased the keratin of the crest and beak by percentage. Levi bernardo (talk) 06:29, 2 April 2024 (UTC)

Banji.

Banji illustration almost ready. Levi bernardo (talk) 03:23, 11 April 2024 (UTC)

Here is an progress of Lepidus. Levi bernardo (talk) 21:39, 17 March 2024 (UTC)

Modifications applied to Lepidus, I will add details to the hands and others to the head later. Levi bernardo (talk) 05:59, 2 April 2024 (UTC)

Chakisaurus now has color. --Levi bernardo (talk) 06:43, 17 March 2024 (UTC)

The background individuals are admittedly a little distracting. Lythronaxargestes (talk | contribs) 14:33, 18 March 2024 (UTC)

The plan was to make a non-lateral illustration that will also show the refieres juvenile specimens to the genus. I think I will have to add details to them so that they are better aesthetically and also if possible some more background. Levi bernardo (talk) 06:02, 2 April 2024 (UTC)

Details added to Brighstoneus. Levi bernardo (talk) 11:09, 18 April 2024 (UTC)

Adelolophus

Adelolophus.

Hello again, now I will try to go in alphabetical order of the illustrations that I had left unfinished, I will start with Adelolophus and this is the progress I have, I increased the size of the crest so that it becomes a true parasauroloph adult and not a subadult. I think I need to review and correct the medial process area of the premaxilla. comments? --Levi bernardo (talk) 06:43, 17 March 2024 (UTC)

Shouldn't the keratinous part of the beak extend even further downwards, as we know from at least one Edmontosaurus specimen? The shape of the beak didn't really follow the shape of the jaw tips closely. FunkMonk (talk) 15:43, 18 March 2024 (UTC)

yes, Funkmonk is correct. Beak should be shaped like a hoe rather than a duck's bill. Additionally, someone should digitally clean up the scanner noise. Skye McDavid (talk) 15:01, 22 March 2024 (UTC)

Provisionally ready and added the beak modification mentioned by FunkMonk, plus I corrected what I had said was missing. Thank you. I made the correction digitally, then I will do it physically. Comments? Levi bernardo (talk) 05:57, 2 April 2024 (UTC)

In my opinion it's well made. Aventadoros (talk) 07:26, 2 April 2024 (UTC)

It's fine as a speculative Parasaurolophin but I don't think something this speculative is appropriate for an infobox photo. Skye McDavid (talk) 23:52, 4 April 2024 (UTC)

Good point. Well, i wasn't the one who added it, but we'll definitely have to make a fossil illustration or find a photo of the fossil that has a CC license. Levi bernardo (talk) 02:56, 5 April 2024 (UTC)

Holotype illustration.

So after what was said above, I took the initiative to look for available images of the Adelolophus fossil, but I did not find anything specific. Until I saw that Angel A. Ramirez-Velasco's diagram of North American hadrosaur skulls was available because the article is hosted in a journal with a proper CC license. The problem with the image is that although the illustration of the fossil and the diagram of the silhouette of the skull were extracted with high resolution, it is still a miniature. So I started making a real-size illustration of the fossil in its real colors and this was the result. I think I will make a version that also includes the other available views of the fossil. And although I hate black and white images of fossils, I think the illustration I made looks just a little better in gray, so the future composition will be in grayscale. ––Levi bernardo (talk) 20:12, 28 May 2024 (UTC)

Adelolophus holotype.

The multiple view illustration, made in graphite, is ready. Levi bernardo (talk) 21:30, 8 July 2024 (UTC)

Huanansaurus

Huanansaurus

Since I was illustrating Banji I decided it was time to fix and improve the illustration I had of Huanansaurus as I had already said I would do. Comments? --Levi bernardo (talk) 06:14, 2 April 2024 (UTC)

Maybe it's the shading, but the lower jaw looks much skinnier than the upper jaw. This doesn't track with the mandibular symphysis being described as "short and broad". Lythronaxargestes (talk | contribs) 04:08, 30 May 2024 (UTC)

I made corrections regarding the bony "tooth" area to give it the appearance it should have and to correct an obvious and glaring error. I had tried to investigate this matter by researching the anatomy of oviraptosaurus skulls but I had not found much about it the first time and I had already come across illustrations that correctly reconstructed the "tooth" but I had ignored them. I enlarged the area of the lower jaw just behind the beak by just a percentage, I think that with that and with the correction to the correct anatomy of the "tooth" they should give a thicker appearance. What is true is that the jaw here is just a little open, when it is completely closed it makes its appearance even thinner and smaller. (Note that the head has a taller appearance due to the percentage increase in potential Keratin in the crest). Thanks, this was the final trigger to reach the correct conclusion of the bony "tooth" Levi bernardo (talk) 11:02, 30 May 2024 (UTC)

That looks much better. Lythronaxargestes (talk | contribs) 00:47, 31 May 2024 (UTC)

Abrosaurus

Abrosaurus

I have made basic updates to Abrosaurus illustration, added lips, (I'm not sure if the way of how the tongue look is appropriate. Maybe not) filled and matched the fenestra areas and added skin to the lower part of the jaw - neck, as well as improvements to the eye area and around it. I will also update the full body illustration later. Now that better photographic images of the skull are available I will redo the illustration I made of the skull. Levi bernardo (talk) 11:09, 18 April 2024 (UTC)

Acantholipan

Acantholipan

I have made basic updates to Acantholipan. I'll add more shadows and textures, and maybe color later. Comments? ––Levi bernardo (talk) 20:34, 28 May 2024 (UTC)

The Acantholipan osteoderm situation is complicated. The authors interpret the spine as deriving from the "posterior thoracic" region, even going so far as to include this in their diagnosis for the taxon. Since this is discussed in some detail, it might be more appropriate to include that in the drawing. -SlvrHwk (talk) 09:25, 29 May 2024 (UTC)

I do not agree with the exact approximate position that they provide for the osteoderm, on the first occasion that they study the specimen they only label it as "a distal thoracic osteoderm that is missing its base" and in the study where it is named it is interpreted as "a posterior thoracic osteoderm." In the illustration, the osteoderm is expressed as a lateral thoracic spine just above the humerus, which was placed based on how it appears in the diagram of Ramírez-Velasco & Hernández-Rivera 2015. (But inverted, since it is neither a basal Nodosaur nor an Edmontonia) Levi bernardo (talk) 11:36, 30 May 2024 (UTC)

It is a dacentrurine but is the neck perhaps too long and flexible? Lythronaxargestes (talk | contribs) 04:10, 30 May 2024 (UTC)

The length is revised and is very directly influenced by Miragaia. Flexibility is logical, at this point it should not be a problem. Levi bernardo (talk) 11:07, 30 May 2024 (UTC)

True, now that I see it, I think there is some muscle and ligament missing from the area where the humerus and radius connect. These Lambeosaurines had thin front legs, but they did need more power in the muscles and ligaments to support weight. Thank you. Levi bernardo (talk) 00:38, 30 May 2024 (UTC)

Afromimus

Afromimus

Due to Kiyacursor's recent description, I racked my brain thinking about which group it really belonged to or what this enigmatic animal that had already changed shape since its description would really resemble. I had commented that perhaps I would finish the naosaurid-type version and that perhaps I would make a version where it is interpreted as a Naosauridae taxon sister to Kiyacursor and similar to Berthasaura and Limusaurus + Elaphrosaurus. I made a drawing of Kiyacursor that will serve as the basis for Afromimus. Any opinion and suggestion is completely welcome, the truth is I have been very unsure of how to proceed that is why I have delayed and paused this particular drawing for a long time. --Levi bernardo (talk) 08:18, 21 July 2024 (UTC)

Albalophosaurus as a basal pachycephalosaur

I have made basic updates and added color to Albalophosaurus. Now that it was published that Albalophosaurus could be the most basal member of Pachycephalosauria I also decided to make a version that shows it as such, almost a generalized Marginocephalia but with similarities to Goyocephale. The version where it is shown as basal Ceratopsia will be edited with one of the previous versions that I scanned just before modifying it to transform into Pachycephalosauria --Levi bernardo (talk) 08:18, 21 July 2024 (UTC)

Indeed end of tail is odd, but rest looks good for me. By the way I have the impression that UDL's Lythronax has too skinny legs and scales too differ between the neck and head. In my opinion Tarbosaurus has weird body proportions with skinny hindlimbs.

Those images are added to page without review. I personally don't think these are usable, but reviewing is rule... Those images are originated from this document in researchgate,[1] probably author is same as uploader. Before that the images used illustration of Touhou character was uploaded to Commons, I quickly put copyvio template and those are deleted. Not sure about what is happening to Touhou copyright, is using silhouette ok? Ta-tea-two-te-to (talk) 15:03, 14 September 2024 (UTC)

Hello! First of all, I am indeed the dreaded author himself. Originally the images had already been deleted because they contained an image of a Touhou character (the reasons are really simple, I wanted to get out of the typical rule of using a normal silhouette, anime stuff). The original image could be used but since it violated the copyright anyway I updated the contents with normal silhouettes (these just in case come from Freepik under a free use license as long as the source and the name of the entity that uploaded the silhouettes are indicated, which in this case is rawpixel). The Taikicetus with that Touhou silhouette is almost an experiment to see if the alert also went off with a mere silhouette of the character. They had already left a message warning that if I didn't get evidence of permission from the original author it would be deleted anyway, however the author seems to have been inactive for quite some time, and he still hasn't answered my message. So if there are problems with that version of Taikicetus anyway I wouldn't be upset if it were deleted. But I am curious, what exactly is wrong with the rest of the images? What would be necessary for their use to be valid? Dotkamina (talk) 16:20, 14 September 2024 (UTC)

The copyright situation of the images is still questionable. "Free use" is not explicitly something that is allowed on Wikipedia, especially as their appear to be limitations on what Freepik images can be used for. No NFTs or selling things suggests it would be an NC license which we do not allow, but it is not explicit.

Beyond the copyright status, these images are lacking in some other standards for the wiki. Copyright labels are not allowed, large blocks of text are highly discouraged and in this case detract from the original artwork, and there are some anatomical details that should be adjusted.

My recommendation would be to crop the images to *only* the artwork that you have drawn, so copyright questions and extraneous details are removed, and then re-evaluate the anatomical accuracy of the pieces. IJReid ^{{{T - C - D - R}}} 17:53, 14 September 2024 (UTC)

Well, as you recommended, I have cut the images down to just the drawings. I would like the images to be subject to review for anatomical accuracy. I would like to say in advance that of all the images, I believe the most accurate is the one of Regnellites, given that there are fossil images available, as well as accurate data on its dimensions.

P.S.: The system wouldn't let me add images directly, sorry if it's annoying to have to put links to cropped images this way. Dotkamina (talk) 02:19, 15 September 2024 (UTC)

Looking at least at the dinosaur reconstructions, I think there is a common issue of misshapen and disarticulated limbs. I am also not sure if there is merit in restoring Wakinosaurus given that it is a tooth taxon. Lythronaxargestes (talk | contribs) 03:30, 18 September 2024 (UTC)

Taikicetus is a mysticete, hence the extreme bending of the tail looks to be impossible to me. The Morrison Man (talk) 10:00, 18 September 2024 (UTC)

I agree with Lythronaxargestes that it's pointless to include a reconstruction for Wakinosaurus. It is a tooth taxon of indeterminate position within Theropoda, and this reconstruction has several problems for any theropod. Albalophosaurus basically looks like a Psittacosaur here, especially with the prominent jugal horn that Ohashi & Barrett describe it as *not* having. Don't have anything to say about Hokkaidornis but I'm far from an authority on Cenozoic birds so don't take this an endorsement of accuracy. Agree with Tim on Taikicetus. Skye McDavid (talk) 13:35, 18 September 2024 (UTC)

Additionally, the Taikicetus and Regnellites should be reviewed at Paleoart Review rather than here. I will be posting them there for non-dino wikipedians to comment on. Skye McDavid (talk) 13:39, 18 September 2024 (UTC)

I agree.Wakinosaurus is inaccurate and shrink-wrapped. A more accurate reconstruction should probably be created, and maybe reconstruct it as a megalosaurid if possible? Great Blue Windrunner (talk) 20:03, 1 October 2024 (UTC)

Wakinosaurus is unusable (I think the shrink-wrapping is the least of the issues...), but that doesn't mean it should have a replacement restoration. As was mentioned already, it is a tooth taxon of uncertain affinities. Any kind of restoration will be excessively speculative and thereby useless for Wikipedia purposes.-SlvrHwk (talk) 20:20, 1 October 2024 (UTC)

Proceratosaur Minor Changes

I got the approval to update a lot of proceratosaur stuff previously, I just wanted to make sure to post it here aswell. I had a lot of conversation about fixing skull graphs and reconstructions with other folk, so most are just minor edits. Kileskus I have completely fixed its size reconstruction and added a skull diagram for it.

Furthermore, should I be allowed to post this entire Proceratosaur size graph under the "Proceratosauridae" section?

SirBlameson (talk) 02:38, 18 September 2024 (UTC)

Considering the crest is unknown in Kileskus, I'm not sure how I feel about restoring it with such apparent certainty. Also, I wouldn't put the cladogram as part of the image given that it may change again in the future. Lythronaxargestes (talk | contribs) 03:26, 18 September 2024 (UTC)

I think its fine. All proceratosaurids for which the dorsal part of the skull is preserved have some kind of midline premaxillary/nasal structure, so it's an appropriate assumption unless someone in the literature has explicitly suggested otherwise. A Cynical Idealist (talk) 04:43, 18 September 2024 (UTC)

Yes, but why not a more conservative crest along the lines of Yutyrannus? Lythronaxargestes (talk | contribs) 04:46, 18 September 2024 (UTC)

Kileskus's crest is based off of Guanlong, almost really just copied and pasted. I could give it more of a shallow crest, but given its material and assigning, it's better to base it off of a smaller bodied proceratosaur than a larger bodied one. It's safer to give it the big crest we know the members had rather than the smaller one, but it's anyone's game for it. I can specify in a caption that the crest is based off what we know from Guanlong.

Also, I can remove the cladogram from the Proceratosauridae image, it was only put there because i made a twitter post with it long ago. With that I can try to space them out more SirBlameson (talk) 08:05, 18 September 2024 (UTC)

In that case, adding a smaller key at the top right would be good. Perhaps the clade name can also go there so you have a nice little box with all the 'data' The Morrison Man (talk) 09:55, 18 September 2024 (UTC)

My main concern is that the size chart is a bit difficult to read. I would suggest either switching all the binomial names to black text or else do a key like the size chart here in place of the embedded cladogram. A Cynical Idealist (talk) 04:41, 18 September 2024 (UTC)

By coloring the names in the cladogram, it can be combined with a key without having to choose one over the other. The Morrison Man (talk) 08:02, 18 September 2024 (UTC)

Gualicho shinyae as a noasaurid

I made this for a project I'm working on, and since all of the reconstructions of Gualicho on the wiki are based on the paper skeletal, I figured I'd submit it here to provide an alternate noasaurid reconstruction.

Definitely NOT Dilophosaurus (talk) 04:42, 21 September 2024 (UTC)

I assume the scale bar is 1 meter? That should be mentioned in the caption. What FunkMonk said about pose on the other ones applies here too but otherwise looks fine. Skye McDavid (talk) 13:59, 23 September 2024 (UTC)

It is good that an alternative reconstruction of Gualicho as a noasaurid was being created. I don't see any glaring anatomical errors, the only thing I would do is add the scale bar value as Skye mentioned above. Aventadoros (talk) 17:03, 23 September 2024 (UTC)

Velocisaurus unicus, Elaphrosaurus bambergi, and unnamed Angeac "Ornithomimisaur"

here are some more pieces I made for the project I thought I'd submit! All three are life reconstructions/size charts, and the first one is Velocisaurus as the page states that it is the smallest noasaur, and imo should provide a visual to go along with it. The second one is Elaphrosaurus as imo the size chart currently on the page feels a little off in proportions and scaling. And lastly we have an unnamed taxon from the Angeac-Charente beds. this one is a little different as the species doesn't have a wiki page, but I figured we could use an image for the page on the formation. The preliminary description recovered it as an ornithomimisaur, but since then multiple researchers have suggested that it much more closely resembles elaphrosaurs, and I agree, so that's how I've reconstructed it here.

I find no records in the literature of the Angeac taxon being recognised as anything other than an ornithomimosaur since the initial publication. Lythronaxargestes (talk | contribs) 04:53, 22 September 2024 (UTC)

No papers have come out since then, but there were among other things a blog post by a French paleontologist suggesting this, and observation seems to support that idea as it much more closely resembles an elaphrosaur than any known ornithomimid. The reason no papers have come out testing the idea that it's a noasaur is likely simply that a description has not been published yet and therefore it can't be tested. Definitely NOT Dilophosaurus (talk) 05:28, 22 September 2024 (UTC)

Yeah, we should generally only reflect reliably published ideas, so that might be problematic. FunkMonk (talk) 11:18, 22 September 2024 (UTC)

Fair enough, how about the other two? Definitely NOT Dilophosaurus (talk) 16:19, 22 September 2024 (UTC)

The anatomy seems fine, but a general issue I see in some of them is that it seems like their center of balance is off, particularly Elaphrosaurus and Shaximiao. Like their feet are too far forwards compared to the ankle and knee, and they would tip backwards if just standing in that pose. FunkMonk (talk) 16:41, 22 September 2024 (UTC)

That’s the pose used by the main skeletal I referenced, made by someone I def trust. Honestly it doesn’t seem that off to me. In life it would probably not be so off balance that the animal couldn’t keep itself upright. Definitely NOT Dilophosaurus (talk) 16:52, 22 September 2024 (UTC)

The biggest issue is just that at this point it would be very difficult to repose it without messing up the colors. (I also won’t have access to the project file for about a week.) Definitely NOT Dilophosaurus (talk) 16:53, 22 September 2024 (UTC)

The pose would make sense for a single leg if the other leg was offset, but like this with only one visible, it implies both legs are posed the same way in parallel, which would be problematic. But it isn't that huge of a deal, maybe someone else has something to add. FunkMonk (talk) 17:03, 22 September 2024 (UTC)

As with the others, there is no indication of what size the scalebar represents. This can be added to the caption. I've also heard that the Angeac-Charente Theropod may not be an ornithomimosaur but its actual phylogenetic placement is up in the air until it's formally named and described. I agree with FunkMonk's comments about posture. If you don't want to repose it you can add an offset right leg in a lower layer and you won't have to change the colors at all. Skye McDavid (talk) 14:07, 23 September 2024 (UTC)

Sounds good! I won’t be able to add that for a lil bit, but in the meantime do I have permission to add the rest minus the Angeac one? Definitely NOT Dilophosaurus (talk) 16:41, 23 September 2024 (UTC)

A size chart and reconstruction of MNN TIG-6 for the Spinostropheus page, since there are no size charts currently on the page and the noasaurid reconstruction on the page seems far too derived for MNN TIG-6.

I have to agree the Asiatyrannus jaw is not correct. While the angle of the gape is fine, it is out of articulation, the lines where the ventral margin of the skull and upper margin of the jaw meet would be in the middle of the neck. IJReid ^{{{T - C - D - R}}} 17:26, 26 September 2024 (UTC)

Mongolostegus is fairly straightforward; shown as a kind of generalized stegosaur since its phylogenetic position hasn't been tested in depth.

Until arguments are published to the contrary, the diagram includes all of the referred material.

Irritator challengeri reconstruction

Life restoration of the brazilian spinosaurid Irritator challengeri

Hello. I made this reconstruction of the brazillian spinosaurid Irritator challengeri and I would like it to be reviewed so I could upload it on the Irritator Wikipedia page.

Looks good for the most part. I'm not too familiar with the range of motion for theropod hands, but the left one looks unnatural here, with the palm facing too far forward. It would also probably be best to show both arms/hands in a similar pose.

  Therizinosaurus

UnexpectedDinoLesson (talk) 14:26, 10 October 2024 (UTC)

There is no mention in the publication describing Patagotitan that it had osteoderms. I associate osteoderms more with saltasauroids than longkosaurs. Therefore, they should be removed in both Argentinosaurus and Patagotitan. Aventadoros (talk) 12:45, 11 October 2024 (UTC)

Mendozasaurus had osteoderms definitively so their presence on colossosaurs is good. However, Ceratosaurus and Massospondylus definitely did not have osteoderms, so the dark spots that appear to mimic osteoderms or feature scales should be removed. They are acceptable to leave on the very center of the spine in Cerato, but should be much less promiment (likely subdermal) IJReid ^{{{T - C - D - R}}} 16:27, 11 October 2024 (UTC)

Indeed, Mendozasaurus had osteoderms, but as I mentioned earlier neither in Patagotitan nor Futalognkosaurus were found. Can osteoderms therefore be attributed to all colossosaurs? Besides, the systematics of Titanosauria is very unstable and it is difficult to establish good affinities between taxa within this clade. Aventadoros (talk) 16:51, 11 October 2024 (UTC)

Mendozasaurus is by definition a lognkosaur, and has almost always been found to be a colossosaur including in all recent studies. IJReid ^{{{T - C - D - R}}} 17:01, 11 October 2024 (UTC)

There isn't currently evidence to definitively justify giving every titanosaur osteoderms, but support for this feature seems to be increasingly common, e.g. probable basal titanosaur osteoderms from the Açu Formation (?Tiamat). Certainly the logic that "they haven't been described in taxon x and should therefore be removed" is not fully sound. -SlvrHwk (talk) 18:24, 11 October 2024 (UTC)

Agreed. I don't have a problem with osteoderms on Patagotitan or Argentinosaurus, but they should definitely be removed on Massospondylus and I would also recommend removing them on Ceratosaurus. Skye McDavid (talk) 14:28, 13 October 2024 (UTC)

Osteoderms removed on Ceratosaurus; feature scales reduced on Massospondylus. UnexpectedDinoLesson (talk) 20:59, 30 October 2024 (UTC)

Ceratosaurus is known to a have had a single row of osteoderms on the midline of the back, but there's no evidence of osteoderms anywhere else on the animal. Regarding Therizinosaurus, I think it should probably be a little more upright and have a longer neck. The degree of feathering is controversial, but I'm agnostic on the matter. We don't actually know the exact body proportions of Therizinosaurus, so taxa like Nothronychus and Neimongosaurus are the most effective proxies and they appear to have had very long necks at least as long as their tails, if not longer.

Caudipteryx is also half the size and has been proposed to be secondarily flightless. I don't know if the comparison for integument, especially wings, is apt. Ddinodan (talk) 00:13, 26 October 2024 (UTC)

We have plenty of sources suggesting oviraptorosaurs would have used their wings to cover eggs during nesting and for display, and none that indicate they would have somehow shortened their wings after becoming flightless, and that's not exactly what happened to for example ostriches etc. FunkMonk (talk) 00:33, 26 October 2024 (UTC)

I think longer legs and a smaller skull may be warranted; this guy had some funny proportions (see skeletal below). -SlvrHwk (talk) 06:40, 28 October 2024 (UTC)

Yuanyanglong skeletal

• 
  Skeletal diagram

Reconstructed skeleton of Yuanyanglong including the holotype (white) and referred (orange) specimens. Gaps filled with Avimimus/Caudipteryx. I hadn't initially planned on illustrating the full skeleton, but it looked strange with the floating skull so I filled in the tail and neck. Comments appreciated. -SlvrHwk (talk) 06:37, 28 October 2024 (UTC)

Yuanyanglong (UDL)

New genera of 2024

Working on doing them all, will update this as I get through them. All follow their published material, skeletals if available, and close relatives.

Most already have reconstructions on their pages, but maybe these can be used elsewhere (such as the 2024 in archosaur paleo page. I think it would be neat).

Doesn't Datai have a second horn added to its cheek? It seems to me that it is not visible.

Aventadoros (talk) 07:35, 26 October 2024 (UTC)

The reconstructions look well made and I think they will be used for various articles. I have only a minor comment on Datai, as I feel that the second year on the jugal is missing. 2A00:F41:C70:9F9C:A0EC:EAF:FFA:7F0 (talk) 10:13, 29 October 2024 (UTC)

I've added all of them to 2024 in archosaur paleontology, except for Datai. The Morrison Man (talk) 12:13, 29 October 2024 (UTC)

A few more. I'll be redoing Yuanyanglong, and editing Datai, in the next couple days.

Ddinodan (talk) 20:17, 29 October 2024 (UTC)

A few more. Yuanyanglong has been redone, and Datai has been edited to include the other osteoderm.

On what basis do Chakisaurus and Tietasaurus have partial feathered bodies? Is there any evidence to suggest that ornithopods may have had such structures? Aventadoros (talk) 13:29, 6 November 2024 (UTC)

If I’m correct, it’s based on Kulindadromeus. Just because an integument (e.g. osteoderms, feathers) is not found on a specific taxon doesn’t mean it explicitly didn’t have it. Miracusaurs (talk) 06:15, 8 November 2024 (UTC)

It is possible that it was based on Kulindadromeus, but Elasmaria was more derived that this basal neornithischian. I don't know if you can attribute the presence of feathering in other dinosaur groups based on one discovery. Other than that, I have no other comments on Tietasaurus and Chakisaurus.

Found in Commons. Any opinions? Ta-tea-two-te-to (talk) 03:54, 27 October 2024 (UTC)

Are those supposed to be flippers on the hands? FunkMonk (talk) 04:18, 27 October 2024 (UTC)

I think thats just a result of the detailing being a little inconsistent. The Morrison Man (talk) 20:42, 27 October 2024 (UTC)

Either way, the musculature and joints look quite wonky overall. FunkMonk (talk) 22:07, 27 October 2024 (UTC)

I don't think the neck should be so robust where it meets the skull when its so narrow where it meets the body. I don't know of any analogous condition suggested for any other non-avian theropods. A Cynical Idealist (talk) 01:22, 28 October 2024 (UTC)

  Moros

UnexpectedDinoLesson (talk) 00:52, 31 October 2024 (UTC)

Carnotaurus should not have osteoderms. The skin impressions that were previously thought to be osteoderms have been reinterpreted as irregular feature scales. And there definitely shouldn't be more than two unguals on the hands, if any at all. A Cynical Idealist (talk) 01:09, 31 October 2024 (UTC)

Silesaurus should only have three claws on the hand, but should have four toes on the feet. IJReid ^{{{T - C - D - R}}} 17:20, 31 October 2024 (UTC)

• Don't think I've ever seen Compsognathus restored with such a concave upper surface of the snout? What's that based on? FunkMonk (talk) 17:28, 31 October 2024 (UTC)

  I assume that's just the outline of the antorbital fenestra visible through the skin. A Cynical Idealist (talk) 02:46, 1 November 2024 (UTC)

  The skull of the Compsognathus is based on Scott Hartman's restoration. Not sure if you're asking about the outline, or what is indeed the fenestra. UnexpectedDinoLesson (talk) 19:30, 1 November 2024 (UTC)

Dinosaurs by year (Atlantis536)

Megalosaurus

Megalosaurus

Hey y'all! I'm doing a project where I'm drawing one dinosaur named every year since 1824. Starting with the very first non-avian dinosaur named, Megalosaurus bucklandii. This reconstruction is based on Gunnar Bivens' skeletal on DeviantArt. What do you think? Atlantis536 (talk) 01:16, 1 November 2024 (UTC)

The eye is probably too small, but its otherwise unobjectionable. A Cynical Idealist (talk) 02:45, 1 November 2024 (UTC)

That's the size of the eye minus the sclerotic ring in the skeletal. Atlantis536 (talk) 04:07, 1 November 2024 (UTC)

Keep in mind that the sclerotic ring would be embedded in the eye. The Morrison Man (talk) 08:01, 1 November 2024 (UTC)

FunkMonk said in an archived thread that the visible portion of the eye should match the inner diameter of the sclerotic ring, not the outer. Atlantis536 (talk) 09:09, 1 November 2024 (UTC)

Yeah, another thing, all of them seem to have pretty extensive cheeks, even the theropods? What is that based on? FunkMonk (talk) 09:28, 1 November 2024 (UTC)

The cheeks start where the tooth row ends according to the Megalosaurus skeletal. The Streptospondylus skeletal doesn't show the teeth so I just guessed. Atlantis536 (talk) 09:49, 1 November 2024 (UTC)

One of many licensing/copyright issues in this project; almost all of this is directly traced from Gunnar Bivens' skeletal. While the skeletal is licensed under the Creative Commons, it should be properly cited in your file description. Copyrighted skeletals (like Scott Hartman's, used below) can be referenced but not traced... -SlvrHwk (talk) 00:22, 6 November 2024 (UTC)

• I've mentioned this on one of your past drawings, but it seems you have ignored it here: The hind legs appear to protrude directly from the abdomen. There should still be some kind of delineation for most of the leg to indicate its articulation with the pelvic region. -SlvrHwk (talk) 00:22, 6 November 2024 (UTC)

Iguanodon

Iguanodon

For 1825, here is Iguanodon bernissartensis, based on Scott Hartman's skeletal. Atlantis536 (talk) 04:09, 1 November 2024 (UTC)

I feel like this should go without saying, but apparently a reminder is needed—you can reference a copyrighted skeletal diagram but not trace it. Slightly reposing two of the limbs (the only real differences in silhouette between Scott's Iguanodon and yours) doesn't make it a unique work. Also the manual unguals go beyond the imaginary "floor" plane. -SlvrHwk (talk) 00:10, 6 November 2024 (UTC)

The manual unguals are supposed to slightly protrude towards the viewer. Atlantis536 (talk) 00:52, 6 November 2024 (UTC)

Streptospondylus

Streptospondylus

Next up, for 1832, I have Streptospondylus altdorfensis, based on the skeletal by IJReid on DeviantArt. Atlantis536 (talk) 07:01, 1 November 2024 (UTC)

Hylaeosaurus

Hylaeosaurus

For 1833, here's the oft-forgotten original dinosaur, Hylaeosaurus armatus. It's based on Scott Hartman's Gastonia since the Vectipelta description found Hylaeosaurus and Gastonia to be sister taxa. Atlantis536 (talk) 10:17, 1 November 2024 (UTC)

A Gastonia clone probably isn't the best basis for Hylaeosaurus since the latter's polacanthid/-ine affinities aren't consistently supported. Regardless, this drawing doesn't seem to accurately represent the distinct cervical–pectoral lateral osteoderms of Hylaeosaurus, and the unfounded stegosaur-like caudal spines are a bit too speculative for Wikipedia purposes. -SlvrHwk (talk) 00:40, 6 November 2024 (UTC)

The neck spines are supposed to be drawn as if being seen from the side, so they’re not too large here. Also, most depictions of Hylaeosaurus have the tail spines (including the one currently in the article), so I figured it would be okay to add them. Atlantis536 (talk) 00:54, 6 November 2024 (UTC)

Thecodontosaurus

Thecodontosaurus

For 1836, have the basal sauropodomorph Thecodontosaurus antiquus. This reconstruction is based on Jaime Headden's skeletal while the coloration is based on the Agrosaurus I submitted here a while back. Atlantis536 (talk) 12:31, 1 November 2024 (UTC)

Plateosaurus

Plateosaurus

Another sauropodomorph -- this time Plateosaurus trossingensis from 1837. Based on Scott Hartman's skeletal. Atlantis536 (talk) 13:42, 1 November 2024 (UTC)

Cetiosaurus

Cetiosaurus

The first sauropod skeleton known -- Cetiosaurus oxoniensis named in 1841. Based on Dan Folkes' skeletal. Atlantis536 (talk) 01:06, 2 November 2024 (UTC)

Regnosaurus

Regnosaurus

For 1848, have a mysterious dinosaur, Regnosaurus northamptoni. This reconstruction is based on the skeletal provided by Tracy Ford on Paleofile.com, itself based on Barrett and Upchurch (1995)'s interpretation of it as a huayangosaurid. Atlantis536 (talk) 03:30, 2 November 2024 (UTC)

Regnosaurus is one of those taxa that I am uncertain really benefit from a life restoration on Wikipedia, given the limited known material and very unresolved taxonomic affinities. Nevertheless, Tracy Ford's skeletals are not rigorous and shouldn't be used as a reference (see also Polacanthus below). -SlvrHwk (talk) 00:51, 6 November 2024 (UTC)

Pelorosaurus

Pelorosaurus

For 1850, here's Pelorosaurus brevis. Based on Nima Sassani's skeletal on DeviantArt. Atlantis536 (talk) 05:46, 2 November 2024 (UTC)

Aepisaurus

Aepisaurus

For 1852, have Aepisaurus elephantinus. This reconstruction is based on Scott Hartman's Camarasaurus, since McIntosh (1990) and Le Loeuff (1993) found that Aepisaurus resembled camarasaurids. Atlantis536 (talk) 10:15, 2 November 2024 (UTC)

If Aepisaurus is going to have a life restoration on Wikipedia (which it probably shouldn't), it should be more generalized, not just a Camarasaurus replica. A longer neck might be helpful for this. -SlvrHwk (talk) 01:21, 6 November 2024 (UTC)

I figured Camarasaurus is already generic enough of a macronarian/eusauropod, so I don't think proportion changes are necessary. Atlantis536 (talk) 02:34, 6 November 2024 (UTC)

Massospondylus

Massospondylus

A slightly more well-known dinosaur this time: Massospondylus carinatus, named in 1854. Based on Scott Hartman's skeletal. Atlantis536 (talk) 11:25, 2 November 2024 (UTC)

Troodon

Troodon

A once well-known, now dubious taxon: Troodon formosus, originally named in 1856. Based on Scott Hartman's skeletal of Talos sampsoni. Atlantis536 (talk) 13:45, 2 November 2024 (UTC)

Are the proportions consistent with the new MOR Troodon mount? -SlvrHwk (talk) 01:26, 6 November 2024 (UTC)

Eyeballing it, I think so. Atlantis536 (talk) 02:34, 6 November 2024 (UTC)

Stenopelix

Stenopelix

Back with a basal ceratopsian from Germany: Stenopelix valdensis named in 1857. Based on a skeletal reconstruction by Pete Buchholz on DeviantArt. Atlantis536 (talk) 02:02, 3 November 2024 (UTC)

Hadrosaurus

Hadrosaurus

The first good non-avian dinosaur from North America -- Hadrosaurus foulkii from 1858. Based on a skeletal reconstruction by Genya Masukawa. Atlantis536 (talk) 04:50, 3 November 2024 (UTC)

Scelidosaurus

Scelidosaurus

For 1859, have Scelidosaurus harrisonii. Took me a painfully long time detailing all those osteoderms. Based on Scott Hartman's skeletal. Atlantis536 (talk) 08:59, 3 November 2024 (UTC)

Scott Hartman's Scelido skeletal is nice but outdated. David Norman's recent extensive monograph series contains several updated reconstructions that should be helpful. -SlvrHwk (talk) 01:35, 6 November 2024 (UTC)

I've heard Norman reconstructed the skull too large though. Cisiopurple was asked to update his Scelidosaurus following the same source but someone told him not to because of said error. Atlantis536 (talk) 02:33, 6 November 2024 (UTC)

Archaeopteryx

Archaeopteryx

The original dino-bird, Archaeopteryx lithographica, named in 1861. Based on Scott Hartman's skeletal. Atlantis536 (talk) 10:59, 3 November 2024 (UTC)

Polacanthus

Polacanthus

Polacanthus foxii representing 1865. Based on a skeletal reconstruction by Tracy Ford. Atlantis536 (talk) 05:20, 4 November 2024 (UTC)
