Considering that Dinosauria is part of the class Archosauria, shouldn't Saurischia be part of this same class instead of Reptilia? DarthVader 09:54, 17 July 2005 (UTC)

Agreed, Class Archosauria seems to be standard across the dinosaur entries. Fixing this and the mis-spell of Aves as "Avis" in the taxobox. Dinoguy2 02:33, 9 December 2005 (UTC)

[edit] Visible

Is it possible to see the different types of hips reflected in external form or stance?

The main visible difference in life would have been the size of the "gut"--the back-pointing pubis of ornithischians (and also herbivorous theropods) allowed for a longer digestive track and a longer belly. The more anterior center of gravity created by this may be why so many ornithischians were quadrupeds.Dinoguy2 23:38, 12 September 2006 (UTC)
