The lake cat (Puma lacustris) is an extinct species of Puma from the Blancan stage (from the Late Pliocene to Early Pleistocene). 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.[1] The taxonomic identity has been uncertain at times, as a relationship (and classification) to lynxes has been purposed.[2] Additional specimens of this species of Puma have been found elsewhere in North America, such as Washington, California, Arizona, Texas, and Baja California.[3]
Taxonomy
The earliest lake cat fossils date to 4.18–3.11 MYA and are found in the Blancan Glenns Ferry Formation, Idaho.[4]
Description
Lake cats were medium-sized felines with a size intermediate between modern bobcats and cougars.[5] Remains of lake cats are extremely similar to those of the lynx-like Felis rexroadensis, though fossils of that species are smaller in comparison with the lake cat.[6]
