Dinofelis paleoonca ("terrible cat") is a species of saber-toothed cats belonging to the tribe Metailurini of the family Felidae endemic to North America during the Pliocene living from 4.9—1.8 mya, existing for approximately 3.1 million years.[1]
Taxonomy
Dinofelis paleoonca was named by Meade (1945).[2] Its type locality is Meade's Quarry 11, which is in a Blancan terrestrial horizon in the Blanco Formation of Texas. It was recombined as Dinofelis palaeoonca by Kurten (1972), Hemmer (1973), Dalquest (1975), Kurten and Anderson (1980), Schultz (1990) and Werdelin and Lewis (2001).[3]
