The visitor now finds himself in the Marine Reptile Corridor 

 (No. 405) on the walls of which are displayed several remarkable 

 fossils. The largest of these is of a Mosasaur, a huge Fossil 



marine lizard, 30 feet in length. On the easterly wall Reptiles, 

 are several Ichthyosaurs ; one of these will be seen to be ac- 

 companied with young. 



The Anighito meteorite, weighing more than 6,000 pounds, is 

 temporarily installed in this corridor. 



Passing now towards the east, one enters the Hall of Fossil 

 Mammals (No. 406). The general arrangement of this hall is 

 on the "alcove plan." The collections of the de- Fossil 



partment include the famous Cope Collection. Along Mammals, 

 the north side are groups of fossils illustrating among other 

 forms the origin and development of Primitive Hoofed Mammals, 

 Carnivores, Mastodons, Elephants and Even-toed Hoofed Mam- 

 mals. Along the south side the Titanotheres, Rhinoceroses 

 and Horses receive special treatment. Watercolor restorations 

 show the supposed appearance in life of some of these re- 

 markable animals. The specimens are elaborately labeled and 

 there are special Guide Leaflets, " The Collection of Fossil Ver- 

 tebrates " and " The Evolution of the Horse," which may be 

 borrowed or purchased of the attendant.
