The first vertebrate fossil obtained from the Upper Cretaceous 

 of Kansas was the type specimen of Elasmosaurus platyurus Cope, 

 collected by Dr. Theophilus H. Turner, the physician of the 

 garrison at Fort Wallace, and taken east by Dr. J. L. Leconte. 

 It was described by Cope in Leconte 's Notes on Geology of the 

 Route of the Union Pacific Railroad, 1868, p. 68. 



The next specimen obtained was a part of a cranium of Tylo- 

 sa.urus proriger Cope, the type, collected by Colonel Cunningham 

 and Mr. Minor "in the vicinity of Monument station, and sent 

 by them to Prof. Louis Agassiz." The locality is probably 

 Monument station of the overland route, in the vicinity of 

 Monument Rocks, in the valley of the Smoky Hill river. 

 Other specimens were later obtained by Drs. J. H. Janeway and 

 George Sternberg in the vicinity of Forts Hays and Wallace, 

 and by Mr. Webb, of Topeka. 



The first to make any systematic collections of fossils from 

 the Cretaceous of Kansas was the late Prof. B. F. Mudge, at 

 that time professor of geology in the Kansas Agricultural Col- 

 lege. I was a student at that time under him at this college, 

 and well remember the ardent enthusiasm that he evinced in 

 the discoveries he made. His first expedition, as I remember, 

 was up the Republican and Solomon rivers into the wholly un- 

 inhabited region, the home then of the bison and roving bands 

 of marauding Indians. It was made shortly after the close of 

 the college year in 1870. A chance acquaintance whom he met 

 on the expedition, and who had recently come from Phila- 

 delphia, urged him to send his specimens to a young and 

 promising naturalist in that city who was especially interested 

 in vertebrate fossils. Although Professor Cope was then less 

 than thirty years of age he had already achieved renown among 

 naturalists, and it was to him that Professor Mudge wrote ask-
