Puma lacustris
The lake cat is an extinct species of Puma from the Blancan stage. The type specimen is a partial fragment piece of the right side of the mandible retaining canine and cheek-teeth found in the Hagerman Fossil Beds National Monument from Idaho. The holotype was described in 1933 by Gazin who considered a smaller relative of the cougar. The taxonomic identity has been uncertain at times, as a relationship to lynxes has been purposed. Additional specimens of this species of Puma have been found elsewhere in North America, such as Washington, California, Arizona, Texas, and Baja California.
