The coal-bearing formation above the Lewis shale, near Durango, has 

 somewhat generally been regarded as Laramie because of its stratigraphic 

 position. These beds were found to be very fossiliferous in some places. 

 Some of the fossils throw doubt on the Laramie age of the formation, 

 but for the purposes of this paper it will be called "Laramie^' in order 

 to avoid introducing a new name. Doctor Gardner found several fossils 

 in it and these are named in the foregoing section. The best collection 

 obtained from it by the writer contains both plants and invertebrates. 

 They were found in the west wall of Animas Canyon, half a mile south 

 of Carbon Junction, about 200 feet above the lowest or principal bed of 

 coal. A few fossil leaves were collected from lower horizons in the same 

 formation near this locality by J. A. Taff in 1906, and by J. H. Gardner 

 in 1909. In order to make the flora of this locality complete, these have 

 been included in the following list and are marked thus (*) :
