fossil plants were found by the present writer a few feet above the coal 

 both north and south of the railroad near Dulce : 



Fossil Plants collected from the ''Laramie" near Dulce, New Mexico 



(United States Geological Survey locality number G042) 



(Those marked (*) occur also in the "Laramie" near Durango, Colorado)

Zizyphus n. sp. 



The flora is essentially the same as that described from the "Laramie" 

 of the Durango section, and confirms the statement that the beds are of 

 the same age. It also strengthens Doctor Knowlton's opinion, previously 

 quoted, that the beds may be older than Laramie, inasmuch as two of the 

 species are found at Point of Eocks, Wyoming, in a formation regarded 

 as older than Laramie, and others are found in the Mesaverde at the 

 localities farther south, described in this paper. In commenting on these 

 plants, Knowlton says : "Their age is essentially Montana and not Lara- 

 mie. If uninfluenced by their apparent stratigraphic position, I should 

 incline to place them in the Mesaverde, but since they are above Lewis 

 they obviously can not be Mesaverde, though they can be — and in my 

 opinion are — still Montana." 



The writer found no invertebrates in the "Laramie" near Dulce, but 

 J. H. Gardner collected some from this formation near Pagosa Junction, 

 about 15 miles northwest of Dulce. They are as follows:

The rocks above the Lewis shale in the Dulce area, referable to the 

 Cretaceous, are only about 225 feet thick, including the basal sandstone, 

 which is 60 feet thick. A section of them and of the rocks underlying 

 them was measured in the steep canyon wall about a mile northwest of 

 Dulce. At this locality a conglomerate that varies greatly in thickness
