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 
not 
a convincing argument. The anatomical evidence for saurischian lips is solid 
enough to make it the much superior hypothesis.
