Talk:Ornithurae

Thanks for the input and the taxoboxes, Dinoguy2. We're making a pretty good team, I'd say.Jbrougham (talk) 23:37, 21 January 2008 (UTC)

Agreed, and good work on getting these bird clade articles up! Dinoguy2 (talk) 01:22, 22 January 2008 (UTC)

Phylogenetic position of Ornithurae

I don't get it. In this article, the Ornithurae are placed as an group containing almost all birds, except the very primitive ones (Archaeopteryx and allies). However, in some articles (like Gansus), the Ornithurae seem to be placed under the Pygostyles, and are even considered a sistergroup of Enantiornithes, containing only the Hesperornithiformes and Carinatae (Ichtyornithes and Neornithes), thus being part of Ornithothoraces.

So, what's the true current consensus? Are Ornithurae a clade containing only the Neornithes (modern birds) and close relatives, or are they a much more ancient clade, containing the Enantiornithes and Confuciusornithidae, thus being the parentclade of Pygostylae?DaMatriX (talk) 20:20, 14 June 2009 (UTC)

I don't think there's any real consensus, and probably won't be until PhyloCode adopts an "official" definition. Right now both definitions (pretty radically different) are both in use as far as I know, by different groups of scientists. Dinoguy2 (talk) 22:01, 14 June 2009 (UTC)

Well, most articles on Wikipedia seem to use the other defenition (Ornithurae as clade under Pygostylae and Ornithothoraces), so I suggest we do the same here. What's your opinion? DaMatriX (talk) 19:00, 15 June 2009 (UTC)

I agree with adjusting this down to where the others believe it should be as most seem to agree that is the way. However there should be a section written concerning the disparity. speednat (talk) 03:55, 8 July 2009 (UTC)
