Allosaurus fragilis and Stegosaurus stenops. From this view, one can see the furculae on Allosaurus. This view also shows off the boney ossicles that protected the neck region of Stegosaurus; maybe not so much from attack, but from the sharply pointed leaves of palms and cycads which the animal probably ate.
