Clevosaurus (Late Triassic, Early Jurassic), a diapsid reptile belonging to the rhynchocephalians was used to study the dentary morphospace. Interestingly the morphospace differs from other rhynchocephalians. Finite element analysis indicates that the investigated species had bite forces and tooth pressures sufficient to break apart chitin suggesting a diet including tough‐shelled beetles and possibly small vertebrates. On the jaws…
