DEPARTMENT OF VERTEBRATE PALAEONTOLOGY. 



REVISED LIST' OF CASTS, MODELS, PHOTOGRAPHS, 

 AND RESTORATIONS OF FOSSIL VERTEBRATES. 



This Department of the American Museum of Natural 

 History was estabhshed in May, 1891, as the Department of 

 MammaUan Palaeontology, and was extended to include Verte- 

 brate Palaeontology in 1896. The object of the Trustees is 

 to procure a representative collection of the American Fossil 

 Vertebrates from the successive geological horizons of the 

 West for purposes of exhibition, research and pubhcation. 

 The collections are being made readily accessible to students, 

 and placed upon exhibition as rapidly as they are prepared. 

 Such duplicate original specimens as are available for purposes 

 of exchange are offered to other museums. 



In order to publish as widely as possible the discoveries of 

 scientific and popular interest and to place the knowledge of 

 them within reach of those unable to visit this Museum, a 

 series of plaster casts of specimens and models, and of photo- 

 graphs of skeletons and restorations has been prepared for 

 sale to, or exchange with, other museums, colleges and high 

 schools.
