* The name Knight has been proposed for the tipper part of the Wasatch 

 containing Corvphodon remains. It is taken from Knight Station, a point 

 near the locality where fossils belonging to this genus were first found in 

 North America. Further, the typical Upper Wasatch is extremely well 

 developed around Knight Station. Certain considerations suggest that the 

 Knight formation may be an exact synonym of King's Vermilion Creek 

 formation, but as the writer has not had the opportunity to examine King's 

 type section he has proposed the provisional name Knight pending a study 

 of the Vermilion Creek section. See Prof. Paper 56, 1907, pp. 87-89, 92-96. 



fin the Evanston section, between the beds belonging to the Laramie 

 (Carbon) group and the Coryphodon-bearing Wasatch, are 4,000 feet of 

 strata which have the stratigraphic position of the Fort Union and Puerco. 

 These are here separated from the Coryphodon-bearing portion of the 

 Wasatch by an unconformity of much less magnitude and importance than 

 that of the base of the Laramie (Carbon) beds.
