(Audio is on the quiet side, apologies!)
Tracy Ford explains why Tyrannosaurus rex and its kin did NOT have lips. He shows the impact of the ectopterygoid, tooth size, aestivation, and foramina on the jaw which all lead him to conclude... NO LIPS.
Heterodonty is briefly discussed and Tracy tells us why he doesn't like calling the teeth "killer bananas." The bite force via musculature is pointed out. And Dr. BC shows his soft side...
The two paleo fans also discuss T. rex arms, binocular vision, antorbital fenestra coverings, narial location, speed, occipital condyle and head angle, and then close with something new for Dr. BC to consider... nasal rugosities. Whew!
