THE DINOSAURS 95 



bestowed upon him by Professor Osborn, for, apparently 

 nothing could have withstood the attack of this monster 

 beast of prey unless possibly some relative like Tricera- 

 tops, armed to resist frontal attacks, or that "walking 

 armored citadel," Ankylosaurus, squatting down and 

 striking right and left with club-shaped tail. The ex- 

 istence of this great beast was known from a few leg 

 bones found by Mr. Hatcher before 1890, but these 

 merely hinted at its size and power and it remained for 

 Mr. Barnum Brown to gather the material that made it 

 possible to reconstruct the skeleton, the greatest prize 

 being the huge skull which must really be seen to be 

 appreciated. 



Such were some of the strange and mighty animals 

 that once roamed this continent from the valley of the 

 Connecticut, where they literally left their footprints on 

 the sands of time, to the Rocky Mountains, where the 

 ancient lakes and rivers became cemeteries for the en- 

 tombment of their bones. 



The labor of the collector has gathered their fossil 

 remains from many a Western canyon, the skill of the 

 preparator has removed them from their stony 

 sepulchres and the study of the anatomist has restored 

 them as they were in life.

Most of our large museums have on exhibition fine speci- 

 mens of many Dinosaurs, comprising skulls, limbs, and large 

 portions of their skeletons. The American Museum of Natural 

 History, New York, has by far the largest and finest display, 

 including as it does many unusually complete skeletons and fine 

 skulls: among them are the huge Tyrannosaurus, Brontosaurus, 

 Gorgosaurus, Monoclonius and Struthiomimus. Of special note 

 is the "mummied" Trachodon, showing a great part of the skin 

 of the animal. The first actual skeleton of a Dinosaur to be 

 mounted in this country was the Trachodon at the Yale Univer-
