Professor Cope 1 in describing Styptobasis as a new genus 

 remarked: "This was a large shark of carnivorous habits, and 

 its presence indicates the existence of a marine fauna whose 

 remains have not been discovered." Associated with No. 8 was 

 a huge Pinna nearly three feet long. 



Quarries and exposures were also examined in the vicinity of 

 Wymore, but no additional data were secured, since the sections 

 were the same as at Blue Springs. 



At Odell several slight exposures were found along the bluffs, 

 and one in a small gulch west of the town. From the last one 

 mentioned a single specimen of Chcenomya minnehaha (Swal.) 

 was taken. On account of the exposures being slight, and no 

 chance to study more than a few feet of limestone, the Odell 

 region was not worked over. From a few measurements of rock 

 in place the dip was found to be slightly to the southwest. 



The exposures along the river south from Wymore, |are very 

 numerous and in many places form continuous bluffs, but none 

 of these were critically examined until the Kansas-Nebraska line 

 was reached. Here there were the finest exposures^_seen along
