Alwalkeria's phylogenetic position

Paul Sereno, in the 1990s, showed the herrarasaurids to be basal saurischians. Therefore change the classification to show that Alwalkeria is in the Herrarasauridae but is outside the Theropoda.

Alwalkeria isn't a herrerasaurid. And in any case, Sereno thinks they are theropods. More recent studies have suggested they may be basal saurischians. Read the text of the article, there is a short explanation. Sheep81 22:07, 3 August 2006 (UTC)[reply]

Alwalkeria, a chimera

Remes and Rauhut (2005) demonstrated that Alwalkeria is a chimera. While the dinosaurian remains represent a basal saurischian and belong to Alwalkeria, the non-dinosaurian remains belong to an unnamed crocodylomorph. Therefore, update the Alwalkeria page.
