"there shall be gnashing of teeth" and Working of Jaws
Of course, it's not enough to stride about. The animals which process their enviroment most efficiently tend to be masters of that enviroment. And dinocephalians had pearly whites like no one
else. Dinocephalian teeth weren't the simple stabbing points of their pelycosaur ancestors.
Dinocephalian predators nipped much like the gorgonopsians. However, the teeth of the plant-eating dinocephalians [left] were much more complex. Each
tooth featured a projecting, ledge-like 'heel'. When the jaw was clenched, the teeth interlaced like the fingers of clasped hands. The food caught between the blunt point of one tooth and the heel
of an opposing tooth would be sliced, ground up, or crushed.
