[edit] retention of bipedalism
maybe a preciosity, but wouldn't be more adequate to say that bipedalism was retained in crocodylomorphs than in crocodilians, since the latter is a narrower group, and the contingent group already contains some bipedal croc-likes?

- Good point. Of course there is ambiguity in the text between the traditional and the modern phylogenetic sense, as a defined clade.--MWAK (talk) 16:15, 3 January 2008 (UTC)
[edit] Role of Euparkeria in the science of bird orgins
Broom (1913) discovered the first strong evidence to support a thecodont origin for birds when he described Euparkeria as ancestral not only to birds but also to dinosaurs (Feduccia, 1996). Dingus and Rowe (1998) say that Euparkeria has long reigned as the most important discovery of the twentieth century in terms of archosaur evolution and the origin of birds. The theory that birds evolved with dinosaurs from thecodonts like Euparkeria is supported by the homological study of Tarsitano and Hecht (1980) and the changing views on the origin of appendages discussed by Laurin (2006).
