Camp Supply Locality. 



I was conducted to the following locality by Mr. J. J. 

 Monahan of Camp Supply. 



Section of butte, about three miles west of Camp Supply, on 

 the divide between Wolf and Beaver creeks. 



Capping of butte, a shell agglomerate composed almost 

 entirely of Anomia shells. There are also an elon- 

 gate delicate species of oyster, and a Gryphcea that 

 is difficult to determine, as no good specimen was 

 obtained ; it is probably G. tucumcarii 6 inches. 



Yellow calcareous clays, about _ 15 ft. 



Indurated shell agglomerate, containing 

 Gryphcea tucumcarii Marcou. 

 Gryphcea fomiculata White, very abundant. 

 Anomia. 



Cyprimeria cf. texana Roemer. 

 Gervillia ? 

 Cardium. 



Turritella seriatim-granulata Roemer ? 

 Anchura kiowaiia Cragin ? 

 Schloenbachia. 

 Sharks teeth _ a few inches. 



Yellow calcareous clays, resting directly on the Red Beds. 

 Near the base of this bed is a thin indurated sandy 

 layer that contains many Turritellas, some oysters, 

 etc. Gryphcea fomiculata occurs in the clays below 

 the sandy layer, and was seen in one place resting 



directly upon the Red Beds 40 ft. 



In one place a thinly laminated yellow calcareous 



sandstone was seen resting on the Red Beds. 



Thickness of Red Beds to flat along Wolf Creek 140 " 



The Cretaceous was seen at several places on this divide and 

 probably forms a continuous capping. 



The localities examined by Professor Cope in this vicinity 

 were on the north side of Beaver Creek, between it and the 

 Cimarron.* He says " Oar first object was to examine the 

 red bluffs of Permian or Trias, which bound the canons north 

 and northwest of the post, which form part of the drainage 

 system of the Cimarron. . . . We found that the formation 

 which constitutes the higher levels at the heads of the canons 

 tributary to the Cimarron is an impure friable calcareous lime- 

 stone of evidently lower Cretaceous age." The following is a 

 revised list of the species of mollusks collected by Professor 

 Cope :f
