Phylogenetic position

I thought it could be worth mentioning that the studies by Wang et al. (2018)[1] and Hartman et al. (2019)[2] concluded Archaeopteryx was closer to Dromaeosauridae and Troodontidae than to Neornithes. Mortimer's "Theropod Database" agrees with Hartman's proposed phylogeny on multiple aspects, including Archaeopteryx's position.[3]Kiwi Rex (talk) 01:42, 1 December 2019 (UTC)[reply]

I really don't have the expertise to write that up, but I suppose it could start off by elaborating the main hypotheses (Archaeopteryx is closer to birds than other dinosaurs, Archaeopteryx is closer to other dinosaurs than to birds [e.g. the Lori paper], and of course maniraptorans are not in actuality coelurosaurs, then elaborate each hypothesis, and then go into the question of multiple origins of flight or multiple losses. 138.88.18.245 (talk) 23:16, 6 July 2020 (UTC)[reply]
Some IP replaced ‘bird-like dinosaur’ the short description with ‘bird with saurian features’ Cheers Markbassett (talk) 22:43, 13 January 2022 (UTC)[reply]

Why does not change until this time

Greek name

Archaios in Greek means ‘original’ or ‘from the beginning’; arche being the beginning/origin. It is nothing literally to do with ancient, that’s just a deduction. It is the winged creature that was there first. The ‘original-winged’ if you will. 2A01:C22:B8C8:2F00:FDF1:55C:EE00:A394 (talk) 07:32, 8 July 2022 (UTC)[reply]

Spelling Variation

It seems all of the -ise/-ize words in this article are spelt -ize, since this isn't usually normal British spelling (except oxford spelling) should all of these be changed to -ise or left as -ize? If left as -ize I think there should be a tag saying to use Oxford spelling instead of British english to be clearer. Ertoe (talk) 04:34, 4 August 2022 (UTC)[reply]

Ize is consistent with UK English (Oxford is within the sphere of UK English), both versions can be used. Of course, if "ize" is the version used, it is just important that it's internally consistent, which it seems to be. But I see both "colour" and "color", "center" instead of "centre", etc. FunkMonk (talk) 10:21, 4 August 2022 (UTC)[reply]

Digits on birds' forewings are rather common on extinct birds

The article states, "Archaeopteryx had three separate digits on each fore-leg each ending with a "claw". Few birds have such features," and then mentions a few contemporary birds that have a more noticeable vestigial claw underneath their wings. Perhaps it's worth adding that this ancestral wing configuration with actual separate digits and claws (no need for quotes on claws, by the way, suggests they're not quite claws) was retained in many uncontested birds that are extinct now, perhaps all enantiornithes. ("All known enantiornithines were good fliers. The early Cretaceous enantiornithines had toothed jaws, and late Cretaceous ones did not. All enantiornithines had wing digits with claws." -- quote from the article I linked). Wikipedia's own article on the group states they're "the most abundant and diverse group known from the Mesozoic era." 45.234.133.177 (talk) 08:07, 17 October 2023 (UTC)[reply]

The secondary flightlessness hypothesis may be relevant to mention here

The article mentions that some researchers have found A. to be nested within Deinonychosaurs "and therefore not a bird," but not that long ago other researchers had sort of found the "opposite," Deinonychosaurs nested as a sister group to Archaeopteryx, and therefore possibly/arguably flightless birds. Some have also posited that perhaps juvenile Deinonychosaurs could fly. So, perhaps that's suggestive of something somewhat blurrier. A more recent study (2019) mentioned in the Origin of Birds article, "secondary flightlessness section," also puts Archaeopteryx closer to birds than to Deinonychosaurs. 45.234.133.177 (talk) 08:33, 17 October 2023 (UTC)[reply]
