and extinct species of Bos, Dicotyles, Equus, Tapirus, Ursus, Castor, 
Arvicola, and Lagomys.” 
AS is Seen above, all these extinct genera, with the exception of 
Smilodon, which is replaced by Dinobastis, occur in Kansas. 
“The remains of man have been shown to occur in the gold- 
bearing gravels. Ihave found them (obsidian spear and arrowheads) 
in profusion mixed with the bones of the extinct fauna at Fossil 
Lake, Oregon, in a friable and windblown formation. This man, 
however, so far at least as regards California, was not paleolithie, 
since he made mostly ground pestles and mortars.” 
“There is, therefore, considerable probability that man was a con- 
temporary of the Equus fauna, and the Equus fauna was con- 
temporary with the Megalonyx fauna of the east,’ all of which 
conclusions the evidence from Kansas substantiates. 
The problems of especial interest in the Neocene deposits of Kan- 
sas are the position, thickness and characteristics of the Goodnight 
beds, the determination of the Blanco beds and the relative extent of 
ali of these and of the Equus bedy overlying them. 
As already stated, Marsh is hopelessly befogged on these subjects 
and his published statements are misleading.
