Draft talk:Herrerasauria

Revision of the Herrerasauridae
This webpage should have cites added. Also as usual, Ezcurra (2006) recovered Eoraptor as a basal theropod, more primitive than Neotheropoda, in his cladistic analysis of Eucoelophysis. Alwalkeria is also a basal theropod, based on the similarities to Eoraptor cited by Max Langer in The Dinosauria (2nd edition). Mortimer (2006, online) recovered Agnosphitys, Chindesaurus (incl. Caseosaurus), and Guaibasaurus as basal theropods more derived than Eoraptor. Based on the data listed here, the Herrasauridae page should be updated.

Synonimizing Herrerasauria with Herrerasauridae
Herrerasauridae (Benedetto, 1973) has priority over Herrerasauria (Galton, 1985) since both clades basically have the same definition Herrerasauridae definition is = Da most inclusive clade containing Herrerasaurus but not Liliensternus and Plateosaurus Herrerasauria definition is = The most inclusive clade containing Herrerasaurus but not Passer domesticus

Both clade basically mean the same thing, due to obvious reasons ^^ Because of this i renamed the page "herrerasauridae": on top of that, Nesbitt (2009) doesnt even include Herrerasauria but Herrerasauridae in its formal phylogenetic analisy in Tawa hallae pdf :), and he found herrerasaurids to be the most basal clade of theropods, even more basal than Eoraptor —Preceding unsigned comment added by Brisio (talk • contribs) 22:22, 10 December 2009 (UTC)
