1 The name “ Knight” has been proposed for the upper part of the Wasatch con- 
taining Coryphodon remains. It is taken from Knight Station, a point near the 
locality where fossils belonging to this genus were first found in North America, and 
where the typical upper Wasatch is extremely well developed. 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 Professional Paper 56, 1907, pp. 87-89, 92-96. 
2 In 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 at the base of the Laramie (Carbon) beds.
