NO. 7 MAMMALIA FROM THE ALMY FORMATION GAZIN 3 



with the underlying Paleozoic limestones in Buckman Hollow, a rela- 

 tionship, of course, of a strictly local character. The various fossil 

 sites are nearly all very low in the section and at the topographic 

 saddle formed at the head of the ridge bounding Buckman Hollow on 

 the southeast scattered remains were found to within only a few feet 

 of the underlying limestone. A locality on the southeast side of this 

 ridge and nearer the road, which produced the type of Phenacodus 

 almieiisis, would appear to be a little higher in the section. P. al- 

 miensis, however, is well represented by materials from the lowest 

 levels so that the stratigraphic difference in this instance would not 

 appear to have faunal significance.

 lections and an indication of the number of specimens recognized as 

 representing each:

AGE AND CORRELATION OF THE FAUNA 



The fauna above listed is beyond doubt a Clarkforkian assemblage. 

 It is interesting to note, moreover, that all the genera, except Car-
