THE FOSSIL FIELDS OF WYOMING 



times found something new to science; and I consider the field 

 still exceedingly rich in this material, to anyone who wishes 

 to investigate such things. 



On March 7, 1877, I found, one and one-half miles 

 from Como Station, on the Union Pacific, the bones of some 

 dinosaurs. These were the first found m the Rocky Moun- 

 tain region. I commenced work on this material on the date of 

 discovery and shipped one ton of these bones to Professor Marsh 

 in the month of June the same year. Then Professor 

 Marsh sent out Dr. S. W. Williston, now in the University of 

 Chicago, Chicago, Illinois, to look after the work for a short time. 

 Dr. Williston and myself worked in this quarry about one year 

 and took a good portion of three skeletons out of it. About 

 this time Professor E. D. Cope of Pennsylvania put a party into 

 the field and there was much competition between the 

 Cope and Marsh parties for several years. Many valuable 

 discoveries and a great addition to scientific information resulted. 

 This material, collected from 1877 to 1888, was divided 

 between the Smithsonian Institution, at Washington, and Yale 

 Museum. Professor Cope's collection was shipped to Phila- 

 delphia where he investigated and made some valuable restora- 

 tions. After his death the collection was sold to the American 

 Museum, Natural History, New York, and is among its 

 mort valuable possessions to-day. Since 1888 the American 

 Museum, the Carnegie Institute at Pittsburg, the Field Colum- 

 bian Museum at Chicago, Harvard University, and Princeton 

 University have had parties in this region nearly every year 

 and an immense amount of fossils has been discovered and 

 shipped to the different institutions. 



Wyoming University commenced in 1 895 to collect material 

 for a museum. This has been carried on to the present time,
