[edit] Class
Dinoguy2, your Aves change points up a problem in taxonomy. What class do non-avian avialae belong to? Reptilia? The current class system is paraphyletic and, thus, pretty artificial.Jbrougham (talk) 15:12, 26 December 2007 (UTC)
- Yup. Actually, Sauropsida, since we're generally using Benton as a source for Linnean ranks.[1] Classification is artificial by definition. Phylogeny is not, but that's not really classification. Nobody has ever named a class Avialae so using one here is original research. Dinoguy2 (talk) 16:09, 26 December 2007 (UTC)

[edit] Status of enantiornithines
Kurochkin (2006) shows the enantiornithines, along with archaeornithines, to be theropods, thereby forming the clade Sauriurae. This means that the clade Enantiornithes is not related to Ornithurae.

[edit] K-T extinction / survival
Does anybody have any evidence-based theory on why the Enantiornithes went extinct at the K-T boundary and the Ornithurae didn't? -- Writtenonsand (talk) 07:50, 22 March 2008 (UTC)
