About Pogonodon

Pogonodon is an extinct genus of cat-like nimravid endemic to North America during the Oligocene from 32.0 to 25.9 Ma. Including supplementary materials The genus the consists of two species P. davisi and P. platycopis. Pogonodon was the last nimravine to go extinct in North America, possibly due to competition with amphicyonids and expansion of grasslands. Its extinction marked the beginning of the cat gap, a 7 million year period without any cat-like predators in North America.

Nimravids wouldn’t reappear in North America until the arrival of barbourofelines, Albanosmilus whitfordi and Barbourofelis.
