Titanotheres from the Titus Canyon formation, California

The Titus Canyon formation of Oligocene age, occurring in the Death Valley region of California, was described in a recent paper by Stock and Bode.(1) Brief mention was made at that time of the fossil mammals found in this formation. Among these, the titanotheres were the first to be discovered and moreover are known by the best preserved material. These types possess special interest because of their relationships. They likewise record for the first time the presence of titanotheres in the lower Tertiary of the Great Basin Province. It should be recalled in this connection that titanotheres have been described recently from the Sespe uppermost Eocene of southern California.(2)
