After Osborn, from a drawing by Charles R. Knight THIS FORMIDABLE DINOSAUR, THE LARGEST OF THE CARNIVOROUS FORMS, WAS SOME 40 FEET IN LENGTH (SEE PAGE 413) It must have presented a most imposing sight as it stalked about in search of food. The great 5-foot jaws were armed with long and sharp teeth, capable of tearing the tough skins of such antagonists as the great Triceratops of the same period (p. 408). This latter creature could not escape by running away, and so was forced, no doubt, to back into some dense forest growth whenever possible, presenting merely its sharp-horned head to its adversary. After Osborn, from a drawing by Charles R. Knight THIS GREAT CARNIVOROUS DINOSAUR HAS BEEN KNOWN FOR SOME YEARS PAST, BUT ONLY RECENTLY HAS A COMPLETE SKELETON OF IT BEEN PLACED ON EXHIBITION The creature is depicted feeding upon the remains of a Brontosaurus, whose actual verte brae, chiseled by the sharp teeth of some similar creature, are placed beneath the mounted skeleton in the American Museum.
