So, dinosaurs...

...come in two "flavors," right? Bird-hipped and lizard-hipped.

Well, now paleontologists aren't sure that's the most important division any more, and are paying more attention to other aspects. Oh, and the first dinosaurs were bipedal - the quadrupeds actually went back to being quadrupedal (Of course, all surviving "dinosaurs" are bipedal, so...)
