Decoding dinosaurs' cryptic anatomical features
It's often easy to interpret a dinosaur's distinctive characteristics. Tyrannosaurus rex almost assuredly used its banana-size teeth to crush bones and to rip flesh from a carcass. Immense sauropods such as Paralititan and Brachiosaurus probably used their remarkably long necks to browse on treetop vegetation. Features on other dinosaurs are more enigmatic.
Consider the plates on Stegosaurus and the domed skulls of pachycephalosaurs. Scientists have proposed various explanations for these and other bizarre body features of dinosaurs.
