Denticle Morphometrics and a Possibly Omnivorous Feeding Habit for the Theropod Dinosaur Troodon.

As in many carnivorous vertebrates, the teeth of most theropod dinosaurs are characterized by serrations. Denticle size (or serration coarseness) and its inverse, serration density, scale with relation to absolute tooth size along the same allometric curve for most groups of carnivorous vertebrates. One of the few fossil groups traditionally interpreted as carnivorous that does not follow this sam…
