The following section was made on Cheyenne canyon : 
Feet 
8. Tertiary to top of hill ±25 
7. Dark brown to black ferruginous sandstone with numerous 
dicotyledenous leaves 6 
6. Whitish to yellowish clays with beds of shale, iron concre- 
tions and sandstone 55 
5. Sandstone like No. 3 with bands and concretions of clay 
ironstone containing leaves, shark's teeth and fish ver- 
tebrae 15 
4. White to yellow clays with bands and lenticular masses of 
sandstone 30 
3. Massive gray to brown sandstone, slightly cross-bedded 5

to one foot thick, and occasional lenticular masses of sand-

The entire section, except No. 7, is characterized by the 
presence of bands, concretions and pockets of clay ironstone 
which break with a conchoidal fracture and cover the slopes. 
Dicotyledenous leaves were found in all parts of the section 
above No. i, becoming more abundant toward the top. It was 
from the ledge corresponding to No. 7 that the leaves men- 
tioned in the paper, "On a Series of Transition Beds, etc.," 
were found.* The Chatman creek locality where Dr. Ward 
and the writer first found fossil leaves in October, 1897, is not 
to exceed one mile west of Cheyenne canyon. 
2. Fossils. 
The first discovery of fossil leaves in the Dakota of the 
region was made by professor Cragin. In his Upper West 
Bear creek section he mentions a ledge of forty feet of "Dark 
brown to yellowish Dakota sandstone containing meager frag- 
ments of dicotyledenous leaves. "t No descriptions were made 
however. On October 3, 1897 Dr. Ward and the writer col- 
lected over one hundred specimens of leaves on Chatman 
creek. Dr. Ward identified the following species: J
