ANIMALS OF THE PAST 



before whose huge frames 

 the bones of the Mam- 

 moth, that famihar by- 

 word for all things great, 

 seem slight. 



For Brontosaurus, the 

 Thunder Lizard, beneath 

 whose mighty tread the 

 earth shook, and his kin- 

 dred were from 40 to 60 

 feet long and 10 to 14 feet 

 high, their thigh bones 

 measuring 5 to 6 feet in 

 length, being the largest 

 single bones known to 

 us, while some of the 

 vertebrge were 4|^ feet 

 high, exceeding in dimen- 

 sions those of a whale. 

 The group to 

 which Brontosaurus 

 belongs, including 

 ^^ Diplodocus and 

 Fig. 19— A Hind Leg Morosaurus, is dis- 



of the Great Bi-ontosaurus, tiuffuished bv a 

 the Largest of the Dinosaurs.
