Hello dinosaur editors. I'm afraid this article doesn't quite meet the FA criteria anymore in terms of being well-researched. There are quite a few bits that are out of date.

This article is written in American English, which has its own spelling conventions (color, defense, traveled) and some terms that are used in it may be different or absent from other varieties of English. According to the relevant style guide, this should not be changed without broad consensus.

Dinosaurs are

Not reptiles, if we include birds as "feathered dinosaurs" - so what is the best way to resolve this inconsistency? If birds are a surviving lineage of dinosaur, but are indeed not dinosaurs because they are descendants (and thus "birds"), then Dinosaurs "were". A suitable analogy is that chimpanzees (Pan) are one of the class of great apes, but are not apes themselves...or, perhaps change "reptiles" to "a class of extinct reptiles and also modern birds"? Hires an editor (talk) 18:47, 16 September 2020 (UTC)

This really gets into exactly what the words "reptile" and "dinosaur" and "bird" mean. By layman terms, they are all mutually exclusive except for maybe "dinosaur" < "reptile". By modern scientific terminology, birds are dinosaurs, which are also reptiles. There have been many talk page discussions on this subject, but at least in my view the current article does a reasonable job of presenting current scientific thinking with the necessary caveats. Lythronaxargestes (talk | contribs) 19:38, 16 September 2020 (UTC)
birds are reptiles but not really. if you follow that birds are reptiles then humans are fish. Clone commando sev (talk) 23:29, 16 September 2020 (UTC)
Again, there's a scientific basis behind saying something like that, but not a lay basis. Lythronaxargestes (talk | contribs) 00:02, 17 September 2020 (UTC)
(edit conflict) But its in current scientific usage. If you look at Google Scholar, there is six thousand hits for non-avian dinosaurs, as scholars see birds as dinosaurs and thereby use the term "non-avian dinosaurs" if they want to exclude them. No such cladistic usage of "fish" exists, as far as I'm aware. --Jules (Mrjulesd) 00:10, 17 September 2020 (UTC)
ok a better example would be calling an early fish a cyanobacteria. Clone commando sev (talk) 00:13, 17 September 2020 (UTC)
But that's just literally not correct? Eukaryotes did not come from bacteria. Lythronaxargestes (talk | contribs) 00:30, 17 September 2020 (UTC)
oh i must be confused. i thought that cyanobacteria was the first life? Clone commando sev (talk) 00:36, 17 September 2020 (UTC)
Surely you mean multicellular life? Lythronaxargestes (talk | contribs) 03:27, 17 September 2020 (UTC)
yes. did eukaryotes evolve from cyanobacteria or are cyanobacteria the first eukaryotes? Clone commando sev (talk) 04:20, 17 September 2020 (UTC)
Neither? It's in the name. Bacteria. "Eukaryote" doesn't mean "multicellular". Lythronaxargestes (talk | contribs) 13:17, 17 September 2020 (UTC)

Dinosaurs are reptiles. Birds are dinosaurs. Birds are reptiles. That's it. It's an open and shut case and anything else is inaccurate. 98.10.3.178 (talk) 03:05, 3 October 2020 (UTC)

Dinosaurs are reptiles, birds are dinosaurs, so birds are reptiles. They are not separate from reptiles as the article now implies

This opening sentence is inaccurate from a scientific standpoint:

Dinosaurs are a class of extinct reptiles and modern birds of the clade Dinosauria.

It is highly inaccurate to present birds as being separate from other reptiles. It goes against modern phylogenetic classification, in spite of what some people on here have stated. Their arguments make no sense if they are viewed scientifically and cladistically. I'd like to request that the opening sentence to be reverted to its previous state to read as follows:

Dinosaurs are a class of reptiles in the clade Dinosauria.

This is all the opening sentence needs. It is accurate and the article explains the differences between dinosaurs and extant "traditional" reptile groups. Birds are not a separate class of animals in modern phylogenetic classification. They should not be presented as such in any accurate article any longer.

98.10.3.178 (talk) 03:03, 3 October 2020 (UTC)

I have reintroduced earlier wording, latest edits created problems. Jules (Mrjulesd) 03:27, 3 October 2020 (UTC)

I thank you very much for doing that Mrjulesd! That opening sentence really made no sense. I appreciate your editing it!! 98.10.3.178 (talk) 04:16, 4 October 2020 (UTC)

@Mrjulesd If birds are reptiles, why are they birds? That doesn't make sense. Birds are not reptiles. Reptiles are cold-blooded, birds are not. Also, the rest of the article differentiates between birds and other dinosaurs - "avian" vs "non-avian". So by definition, birds are indeed dinosaurs, and are not reptiles. Hires an editor (talk) 21:18, 4 October 2020 (UTC)
Except dinosaurs are reptiles in the phylogenetic sense (which is the only reasonable scientific definition)? It depends on the definition. Lythronaxargestes (talk | contribs) 22:46, 4 October 2020 (UTC)

Where? Lythronaxargestes (talk | contribs) 15:30, 16 November 2020 (UTC)
That probably wouldn't make sense. Maybe there's a place where "are" should be changed to "were" or to "is", but messing up both plural/singular and past/present isn't likely. If you want to point out a specific location that should be fixed, please do. It will be easier if you quote the sentence where the fix needs to happen. 2601:5C6:8081:35C0:2499:DAED:827E:97CA (talk) 18:44, 16 November 2020 (UTC)

Birds

This article would make one think that birds are reptiles. Clearly this isn't so... 139.138.6.121 (talk) 03:34, 17 November 2020 (UTC)

"Other groups of animals were restricted in size and niches"

The article says that "Dinosaurs were the dominant terrestrial vertebrates of the Mesozoic Era, especially the Jurassic and Cretaceous periods. Other groups of animals were restricted in size and niches". I am not sure if such a statement is correct. For example, crocodylomorphs can be called an exception to this. HFoxii (talk) 17:18, 20 November 2020 (UTC)

Yes that seems like a bit of a generalization, it obviously doesn't apply to something like Deinosuchus. I think that is more talking about the amphibians and mammals, rather than the reptiles. --Jules (Mrjulesd) 18:28, 20 November 2020 (UTC)

FA criteria

Hello dinosaur editors. I'm afraid this article doesn't quite meet the FA criteria anymore in terms of being well-researched. There are quite a few bits that are out of date.

Examples of (possible) out-of-dateness

  • In the general description-part it says according to a 2006 study, over 500 non-avian dinosaur genera have been identified with certainty so far, and the total number of genera preserved in the fossil record has been estimated at around 1850, nearly 75% of which remain to be discovered. Surely a newer estimate is out there
  • By September 17, 2008, 1,047 different species of dinosaurs had been named. What about now?
  • Paleontologists think that Eoraptor resembles the common ancestor of all dinosaurs cited to 1999 study; do they still think that?
  • ’’ Scientists disagree as to whether non-avian dinosaurs were endothermic, ectothermic, or some combination of both. (2009 source);’’ still true? Or is one now preferred?

Lacking citations

  • The renaissance section is poorly cited. There is a 1986 book without page numbers, and a newspaper article. The newspaper article doesn’t verify all the text in the paragraph before that.

Prose, MOS and citation

  • I find the prose / jargon difficult to understand. The article has a broad appeal, and and much as possible, should be written for a broad audience.
