Re: [dinosaur] Pterosaurs + T. rex bite + Allosaurus + multituberculates + cave lion cubs + more



Sensory bristles around the jaws of anurognathids were reported as
early as 1988 (for Batrachognathus), and Bennett suggested small bumps
on the impression of the jaw as correlates for these in Anurognathus.
