T. rex overbite
Adult T. rexes seem to have a noticeable overbite. This malocclusion begs
the question of how the fleshy, upper-teeth-covering lip model might have
worked. A *lot* of extra gum and lip tissue would be required on the
mandible to meet the upper lip.
Does anyone know of other animals -- living or extinct -- that have/had a
pronounced over- or underbite that could be used as a model for the rex
Does simple bracketing answer the question:
crocodilians (no lips) --> theropod dinosaurs (no lips) --> living birds
Or does the fact that living crocs are all aquatic and the condition in
ancestral crocs is unknown muck this up?
