Review from YCYBenjamin

Hi Dinohk, it's a great page! The structure and flow is fluent, the use of words are precise enough.

1. Good to see you added a diagram of a cross section of a typical theropod and a thin section on tooth replacement. Because last time I don't really understand the anatomy, now it is clear!

2. Significance part is a good idea! Can you add some diagrams describing dental batteries? I'm a little bit lost XD — Preceding unsigned comment added by YCYBenjamin (talk • contribs) 21:07, 20 November 2017 (UTC)[reply]

Review from karaclc

Hi Dinohk!

1. You have added your own image in the Dinosaur dental anatomy session. Just curious are all the structure of dinosaur tooth the same? If no, can you also draw other structure? And it would be quite interesting if you compare the dinosaur's tooth structure to human's/reptile's by contrasting the images.

2. You may add some labels in the image of "Tooth replacement in Coelophysis". For example the incremental lines of von Ebner and the tissue/structures surrounding the tooth.

3. You may include case studies with the dental records. In your page, only Coelophysis's case was reviewd. What about other type of dinosaurs?

4. All the dinosaurs have dental batteries? If it is only some of them, can you give some examples of the dinosaur? — Preceding unsigned comment added by Karaclc (talk • contribs) 06:08, 20 November 2017 (UTC)[reply]

Review from Graeme Bartlett

Hi Raymond.

I thought that this article was going to be about histology. However much of it is more generally about dinosaur teeth, including anatomy and growth, with a few mentions of application of histology. Are you going to write more just on histology? If not this article could be on dinosaur teeth, as there no article written on that yet.

I will say that this draft is quite easy to understand, so that is good. (I expected a lot of technical jargon that would mean nothing to me).

For the image, File:Nigersaurus teeth.png there is plenty of detail that can only be seen when you zoom in. I think it would be a good idea to chop this image into its component pieces, and then show the best ones here along with a key that explains what is visible and what the letters mean - eg S for scratch.

Review from Jupiter

Hi Dinohk.

Your page is about the study of the dental microanatomy of dinosaurs using histology, with a clear description of the preparation of histologic examination and a detailed explanation of different structure of organisms and their parts of dinosaurs. At first, I expected this topic will be different to understand with technical terms, complicated steps and complex explanation. But then I found your page is very easy to understand the follow with simple language, helpful images and clear structure. I really like the way you structure of the "Preparation" and "Dinosaur Dental Anatomy".

Here are some suggestions:

1. In the section "Dinosaur Dental Anatomy", you included a image showing the dental anatomy of Nigersaurus. The pictures in the image are labelled with "A, B, C...", which I do not understand at the beginning. Then, I found there are captions about the labels in the original image, which the labels are representing different part/features. it may be better to add a short note about it in the image caption. so the readers can understand the pictures are representing different parts/features on a teeth fossil.

2. Also, I have checked the page of Histology, in the "Sample preparation" section, there are links to the main article below the subtitle. I found that some of these steps are are similar to your "preparation" section, so may be you would like to add some links as main article if you found the linked page is useful for people to know more about the subsection, , such as Microtome below the "Sectioning" subtitle, such as:

Preparation

Sectioning

Main Article: Microtome (I am not sure if it is a good link, but you can add something like this if you found other pages are giving a more in-depth explanation of your subsection)

3. Just a minor suggestion, you could also include a "See Also" section at the end, with links to related pages, as I found this topic very interesting.

Generally, I really like your page with clear structure and easy explanation on an interesting topic, which was expected to be complex and difficult to understand. Minor changes in picture captions and more links to related pages may be a good idea to make it a good page. Jupmira104(talk) —Preceding undated comment added 08:07, 23 October 2017 (UTC)[reply]

Feedback from Eunicecyl

Hi Dinohk,

I find the page very interesting. However, there are some suggestions that I hope u may find it useful.

1. I think you may consider adding a bit more photos for various sections e.g. tissue types comparison between mammals and dinosaurs perhaps?! and cross sections of dinosaur concentric rings?! to illustrate the points you stated.

2. And its the problem of photos again, I find it hard to understand certain figures, e.g. Figure 1 Bone histology of the dinosaur Shuvuuia and the early bird Confuciusornis (A & B). I clicked on to it and found a description which I have no idea what it is about. It would be nice if all figures come with a simple description, easy for amateurs.

3. I am not sure about the difference between pure dinosaur teeth examining and histology?! Personally, I think you may expand the topic a bit to cover more about dinosaur teeth, e.g. providing "fun facts" like the largest dinosaur teeth ever examined or other evidence of the paleo-environment given by the dinosaur teeth? How can one determines the dinosaurs' behavior, size etc via the teeth? I think it would be nice to include more information about this topic cuz I find it really nice :) — Preceding unsigned comment added by Eunicecyl (talk • contribs) 16:23, 23 October 2017 (UTC)[reply]

Review from YCYBenjamin

Hi, it's a cool page! A few suggestions below:

1. Can you link some jargon words to other wikipedia page? Some concepts may be difficult for normal people to understand, such as ontogenetic stage, Dysalotosaurus and dwarfism.

2. If you are currently doing a project with similar topic as this page, can you take some photos or draw some diagrams/gif showing how the preparation process is done actually. (If possible, im not sure)

3. You showed clear and concise information on this page, perhaps you can add some additional examples about Dinosaur Dental Histology that may help to facilitate other field of research(?)

It's a really nice page with good structure and presentation. Keep it up! — Preceding unsigned comment added by YCYBenjamin (talk • contribs) 18:56, 23 October 2017 (UTC)[reply]

Comments from Patrick

Hi Dinohk, Your page on Dinosaur Dental Histology is well written and reader friendly. The logic flow is easy to follow and understandable technical terms are to the point of a scientific wiki page. The paraphrasing is so good that the procedures and interpretations are listed out systematically. You may consider the followings to improve:

I guess wiki lacks a page or some description for ‘dinosaur teeth’ bridging the logic gap of how dinosaur teeth could interpreted, that’s why I find some terms is hard to understand.
The last few sentences in Background part maybe moved to the introductory paragraph because the non-destructive means of dental histology is inherited with many deficiencies, which makes thin section kind of a must in relevant studies. Another reason is that it echoes the Preparation part which describes how specimen are prepared in destructive means
Similar to the first point, you may consider adding some annotation on the image of ‘dental anatomy of Nigersaurus’, highlighting some of the observations in the figure and its possible interpretations, for instance H shows a dentine and could infer the growth of teeth

Feedback from Jay

1. I like your photo of the Tooth replacement in Coelophysis, but it is difficult to understand where is the cavity and which one is the tooth. Maybe it is better to label them for the readers.

2. As Coelophysis is mentioned multiple times in the article, it may be nice to put a photo of fossil or its interpreted living form in the article.

3. You can add a link to epoxy resin. There is already an article to it under Epoxy. — Preceding unsigned comment added by FieldsetJ (talk • contribs) 02:14, 21 November 2017 (UTC)[reply]
