A Tooth of Hipparion mohavense from the Puente Formation, California

Abstract

Remains of land mammals occurring in Tertiary formations of the Pacific Coast marine province of western North America furnish important data relating to the correlation of the faunal horizons of this region with those of the continental deposits of the Great Basin area to the east. The discovery in marine deposits, presumably the Puente formation of southern California, of a horse tooth identified as belonging to the species Hipparion mohavense Merriam, suggests at once an interesting time relationship between the Puente and the Ricardo deposits of the Mohave desert, the type locality of this species.
