Further Work in Kansas Chalk 1 1 1 



My old friend, Dr. S. W. Williston, who in the 

 seventies was in charge of collecting parties for Pro- 

 fessor Marsh, and is now a noted authority in 

 paleontology and professor of that science in the 

 University of Chicago, describes this specimen in 

 his great work on North American plesiosaurs, a 

 Field Columbian Museum publication. He says: 

 " The specimen of Dolichorhynchops osborni, here- 

 with described and illustrated [Fig. 20], was dis- 

 covered by Mr. George Sternberg, in the summer 

 of 1900, and skilfully collected by his father, the 

 veteran collector of fossil vertebrates. The speci- 

 men was purchased of Mr. Sternberg in the follow- 

 ing spring for the University of Kansas, where it 

 has been mounted and now is. When received at 

 the museum, the skeleton was almost wholly con- 

 tained in a large slab of soft, yellow chalk, with 

 all its bones disassociated, and more or less en- 

 tangled together. The left ischium, lying by the 

 side of the maxilla, was protruding from the sur- 

 face, and part of it was lost. The bones of the tail 

 and some of the smaller podial bones were removed 

 a distance from the rest of the skeleton, and were 

 collected separately by Mr. Sternberg. The head 

 was lying partly upon its left side, and some of the 

 bones of the right side had been macerated away. 

 The maxilla indeed had disappeared.
