Subject: Re: Dinos today? From: The Evil Cub posted Mon, Dec 20 2004, 4:17pm  Okay - A.) You are much more knowledgable than me in this field. All I know I've gotten from reading a few generalist books, and a little bit of historical geology. You're an expert. I'm a dufus. The fact that you're even bothering to respond to my post is a huge compliment. B.) I thought that crocs had hips that were very different from those of at least most dinos we are familiar with. Am I wrong about that? Don't crocs have legs that stick out like lizards (I'm thinking of things like Komodo Dragons when I picture the 'lizard' gait of movement)? C.) I don't know much about taxonomy. But I've seen good arguemnts that dinos should be considered a seperate class, but see (A) above, specifically re: I'm a dufus. You're argument for the clade Archosauria is at leat as good as any other I'm familiar with. But in many ways crocs seem to stand apart from the rest of the reptiles in many ways. I'd be perfectly comfortable concedeing that they are closer to some dinos than most other reptiles. On the other hand, I'm pretty sharp on Roman military history, so I might be able to hold my own there...hehe. Subject: Re: Dinos today?

No, you're right - but the definition of Archosauria is derived from the skull's features, not the limbs. Within the Archosauria, you would have subclades for dinosaurs and crocs. "Don't crocs have legs that stick out like lizards" Kind of. They're a little bit more upright than that, but not fully upright. "I'd be perfectly comfortable concedeing that they are closer to some dinos than most other reptiles" Oh, they are. They're closer to *all* dinosaurs than they are to all other reptiles. V.
