Troodon Posted April 26, 2018 Share Posted April 26, 2018 Theropod dinosaur teeth are usually ziphodont, but the morphology of the denticles varies between species and clades. Gorgosaurus (a tyrannosaurid) and Dromaeosaurus (a dromaeosaurid) both have rectangular denticles despite differences in body size and shape and tooth size. Saurornitholestes (a dromaeosaurid) has pointed denticles that, over time, can wear down to resemble those of Dromaeosaurus. Troodontids (like Troodon) have unique hooked denticles that differ significantly from those of dromaeosaurids. Paper looks at the biomechanics of these different morphologies, not for everyone but interesting. https://www.cell.com/current-biology/fulltext/S0960-9822(18)30371-3 Link to comment Share on other sites More sharing options...
