I might as well uphold my tradition of a review for every nomination, in which case I'll take this one on. On first read the article seems a little shy on some information, but I'm not surprised given the probable lack of papers on a taxon known from a few teeth. I'll continue adding more as I go along. IJReid {{T - C - D - R}} 16:29, 20 May 2020 (UTC)[reply]

Taxonomy:

  • Either some linking to the locations (Chorora Village, Beticha) or some rough approximations of the location (eg. southern Ethiopia) would be appreciated, otherwise the only location information easily identified is the country.
  • Explanation of what CHO-BT stands for would be good
I would assume "Chorora - Beticha"   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
In that case an institution the teeth are held in would be nice, if available. IJReid {{T - C - D - R}} 19:22, 21 May 2020 (UTC)[reply]
it doesn't seem to specify that   User:Dunkleosteus77 |push to talk  23:56, 23 May 2020 (UTC)[reply]
  • Stating they are derived after that they have unique specializations is unnecessary
I like to include the actual term   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
The two phrases are not synonymous, and derived is not used later, so one of them should go. IJReid {{T - C - D - R}} 19:22, 21 May 2020 (UTC)[reply]
I'm confused. Are they redundant or contradictory?   User:Dunkleosteus77 |push to talk  23:56, 23 May 2020 (UTC)[reply]
They are redundant enough that both "derived" should not be included since it is never brought up later in the text. IJReid {{T - C - D - R}} 03:12, 24 May 2020 (UTC)[reply]
I like to include the actual term, like "Hominini (humans and chimps)" instead of just "humans and chimps"   User:Dunkleosteus77 |push to talk  13:11, 24 May 2020 (UTC)[reply]
It should either be incorporated into the sentence "... are derived as they have unique specializations ..." or removed, as it disrupts sentence flow and is not an explanation of what unique specializations mean. IJReid {{T - C - D - R}} 16:03, 24 May 2020 (UTC)[reply]
How would you define derived?   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]
Being derived is a relative term, compared to gorillas Chororap is not derived. Having unique features makes it derived compared to their common ancestor, which is not what the comparisons are to. IJReid {{T - C - D - R}} 21:17, 24 May 2020 (UTC)[reply]
"Because the Chororapithecus teeth have several specializations not shared with those of gorillas (they exhibit a derived condition compared to the presumed last common ancestor), they did not consider it as ancestral to the gorilla."   User:Dunkleosteus77 |push to talk  21:51, 24 May 2020 (UTC)[reply]
  • There is some conflict between the lead and the taxonomy here. The lead says Chororap. is the only fossils of a great ape lineage, but taxonomy says it is the only Miocene fossil, but also that Nakalip. is as well.
Because they didn't firmly say "We classify Nakalipithecus in Gorillini", they simply said it's a possibility, whereas with Chororapithecus, the discoverers said "We classify it in Gorillini, though it is a possibility it is not"   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
Maybe then add the modifications of the phylogeny where nakalipi is either outside or within gorillini to make it clearer its position is less certain. IJReid {{T - C - D - R}} 19:22, 21 May 2020 (UTC)[reply]
done   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]
  • The first sentence of age discussion seems a bit choppy, perhaps split between the original and later interpretation like "... and the discoverers then concluded that the gorilla–human last common ancestor (LCA) existed about 12 mya.[1] The [teeth/deposit] was subsequently re-dated to about 8 mya by [authors], which, if Chororapithecus is indeed a stem gorilla ..."
done   User:Dunkleosteus77 |push to talk  23:56, 23 May 2020 (UTC)[reply]
  • A little mixing of tenses, all but the final sentence of the age paragraph should be past-tense
done   User:Dunkleosteus77 |push to talk  23:56, 23 May 2020 (UTC)[reply]
  • A bit more discussion of the phylogenetic results could add to the article, why Chorora is where it is etc.
similarities with gorillas is in the Anatomy section   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • It is mentioned that is might not be a gorillin, but where would it be if it wasn't?
it would be a stem hominine or hominid, added   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • This paper discusses hominin evolution, and puts forward how previous studies require Chororapithecus to be a hominin to match their proposed MRCA
That's basically the function of "it is possible that Chororapithecus and gorillas instead convergently evolved the same teeth due to a similar diet" and "if Chororapithecus is indeed a stem gorilla". If it isn't a gorillin, then it wouldn't be a crown hominine   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • It is also suggested that Chororapithecus having lateral cusps is the primitive feature for Homininae and also suggests the genus is a stem-hominine instead of a gorillin
added   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • And finally there is this review of phylogeny that should probably be included
added   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • A statement giving the uncertainty of it being a gorillin would be nice, since the papers I found above seem to state the teeth actually differ more than they are similar. IJReid {{T - C - D - R}} 19:22, 21 May 2020 (UTC)[reply]
added   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]

Anatomy:

  • The "molars range in size" should specify that it is adult gorilla size, and also replace "from" with "between"
done   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • "increasing" -> "increase"
fixed   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • Discussion on why a wide base is important would be nice
I'm fairly sure the answer is it makes crushing more effective but it doesn't specify   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • A bit more discussion of why the latter features are important, or comparisons to other animals teeth would add some relevance to the section
added   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]

Paleobiology:

  • An image of a comparable environment would be nice
I'm not aware of anyone making note of a comparable environment   User:Dunkleosteus77 |push to talk  21:07, 21 May 2020 (UTC)[reply]
  • What plants are harder and more brittle?
it doesn't specify, but when I see hard, brittle foods, it generally is in reference to seeds   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
Perhaps then add a statement about what orangutans eat? IJReid {{T - C - D - R}} 19:22, 21 May 2020 (UTC)[reply]
added   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]
  • Looking in Suwa ea 2015, it includes all the ecological information you could need, more about specific fauna from the same locality, from elsewhere in the formation, relative ages, habitat types, and "first sub-saharan mammals from 7-9ma"
I don't know what more I would add that would be relevant to Chororapithecus   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]
Anything about the environment would be good, and the statement about being the first discovery of sub-saharan mammals from the late miocene would be worthwhile adding to the history section. IJReid {{T - C - D - R}} 23:39, 22 May 2020 (UTC)[reply]
added to Palaeobiology   User:Dunkleosteus77 |push to talk  23:56, 23 May 2020 (UTC)[reply]

Other and Lead:

  • The total number of teeth is never mentioned in the article, should be added
added   User:Dunkleosteus77 |push to talk  14:56, 21 May 2020 (UTC)[reply]
  • (and the only other) should be removed, and an entire sentence should be added detailing the possible relationships
the only possible relationships are that it's either in Gorillini or it's not   User:Dunkleosteus77 |push to talk  21:07, 21 May 2020 (UTC)[reply]
The bracketed phrase still messes with the flow of the sentence, it should either be incorporated into the prose or removed. IJReid {{T - C - D - R}} 05:23, 22 May 2020 (UTC)[reply]
removed   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]
  • If information on the describers is available, etymology and some more background could be added to the lead, and the taxonomic aspects could be split into their own paragraph
I think the lead is as big as it should be considering how tiny the article is. It's already bigger than the Anatomy section   User:Dunkleosteus77 |push to talk  18:35, 22 May 2020 (UTC)[reply]

Final comments:

  • I'll let the "derived" discussion stay above, but that one
  • Information on the describers should be given at the beginning of the taxonomy/history section, Suwa and two other authors have articles so they should be relevant enough to be mentioned in context
added   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]
  • Every time the authority of something changes, authors should be mentioned (eg, who redated it, who considered the teeth to be non-gorillin etc)
I mean, everyone acknowledges that it could not be a gorillin   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]
  • "Optional" See Also should be made into three columns, reduced in content, or moved below References
the amount of columns depends on how wide your screen is. My screen shows 3 columns, and See also is always placed before References in my experience   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]
Ah looking at it I can see it is set to the width 25em. I would reduce it to 20em so there isn't as much separation of columns while preserving the look on mobile and other setups. Now optional. IJReid {{T - C - D - R}} 21:17, 24 May 2020 (UTC)[reply]
done   User:Dunkleosteus77 |push to talk  21:52, 24 May 2020 (UTC)[reply]
  • A note about the localities being different ages is good, especially since it means not all listed fauna definitely coexisted
I just listed out the animals from the Beticha locality   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]
  • An image of gorilla teeth should be added to Anatomy (if it exists) if one of those of Chororap cannot be found or made.
added gorilla skull   User:Dunkleosteus77 |push to talk  15:57, 25 May 2020 (UTC)[reply]
  • "Optional" I would personally think splitting the Taxonomy into a History and a Taxonomy section would be better, as then the information about discovery, what fossils, authors etc can be separated from age and classification more cleanly
  • "Optional" An image of Afar Region, Ethiopia should be added to Paleobiology to add a rough environmental context and illustrate the article more
I don't know if the Afar region 8 mya looked like as it is now   User:Dunkleosteus77 |push to talk  17:23, 24 May 2020 (UTC)[reply]

That's about all I have to say, the article, for what's available, is rather comprehensive. IJReid {{T - C - D - R}} 16:03, 24 May 2020 (UTC)[reply]

That's it, good job. IJReid {{T - C - D - R}} 19:16, 25 May 2020 (UTC)[reply]
