100 FOSSIL SEA REPTILES 



the matrix in which the bones are imbedded is carefully chipped away 

 and the missing parts restored in cement and plaster. The bones are 

 then assembled as in life. In the specimens on exhibition the restored 

 parts differ in color from the original parts of the skeleton and can 

 readily be distinguished. 



As a whole, the Museum collections of fossil vertebrates are believed 

 to be the finest in the world, if we take into consideration not merely 

 numbers, but also variety, quality and perfected methods of preparation 

 and exhibition. 



East Corridor 

 FOSSIL SEA REPTILES 



The most noteworthy object here is the skeleton of the flying reptile 

 Pteranodon, having a spread of wing of twenty feet, the greatest flying 

 creature. Above is a great fish, Portheus, with teeth like spikes, and 

 below the sea reptile Tylosaurus: all these lived in or about the sea 

 that covered Kansas and adjoining territory in the Cretaceous period. 

 Opposite are several Ichthyosaurs, sea reptiles from the ancient seas of 

 western Europe. 



South Pavilion 

 HALL OF THE AGE OF MAN 



The South Pavilion is devoted to early man, represented by a series 

 of casts of the more noteworthy specimens, and to his contemporaries, 

 the mammoths and mastodons and the giant ground sloths of South 

 America. 



In front of the entrance is the collection illustrating what is known 

 of the early history of our own race as shown by the remains of early 

 E 1 Man man and the implements used by him. As fossil remains 

 of man are rare and usually very fragmentary, these are 

 represented mainly by casts, but they include examples of all the more 

 perfect and more noteworthy specimens that have been found, such as 

 the Neanderthal, Gibraltar, Chapelle aux Saints, Spy and Piltdown. 



On the left is a series of modern skeletons illustrating the evolution 

 of the horse under the hand of man. Here are such extremes as the Shet -
