Dinosaurs, with Special Reference to the American Museum Collections

The bluffs appear to represent the region of an ancient shoreline, such conditions as we have depicted in the restoration of _Brontosaurus_ (fig. 22)--the sloping banks of a mud...

The sharp teeth, compressed and serrated like a palaeolithic spear point, and the powerful sharp-pointed curved claws on the feet, prove the carnivorous habits of these dinosaur...
