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.
