Re: snarling theropods

I seriously doubt that carnosaurs could make facial expressions, but
Mark Hallet made the excellant point that as land animals, theropods, unlike
crocodilians,who are semi-aquatic, had to be able to conserve thier bodily
fluids. A lipless mouth would dehydrate the sharp tooths faster than you
could say " anatomically incorrect. " I sculpt all of my Saurischians with
lizard lips. Besides, they look cooler that way.
Seems logical, but lots of pterosaurs were flying around with their teeth
hanging out and so have other animals, including saber tooth felids. So it is
a convincing argument. The anatomical evidence for saurischian lips is solid
enough to make it the much superior hypothesis.
