Biology:Pogonodon
Pogonodon is an extinct genus of cat-like nimravid endemic to North America during the Oligocene from 32.0 to 25.9 Ma.[1][2] Including supplementary materials The genus the consists of two species P. davisi and P. platycopis.[3] 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.[4]
Description
Pogonodon was have been similar in size to jaguars.[5] Humerus measurements suggest P. platycopis had a humeral robustness greater than other nimravids, despite having shorter sabers than Hoplophoneus.[6]
Extinction
Pogonodon was the last nimravine to go extinct in North America. Nimravids began to decline globally due to the increase in aridity, which saw an expansion of open environments.[7][8] Pogonodon was able to persist longer than other North American nimravids due to its relative cursoriality. However, it likely wasn't able to compete withe amphicyonids as they were more cursorial and had a generalized dentition compared to nimravids.[4] The extinction of last nimravids such as Pogonodon started the cat gap,[4][8][9] a 7 million year period with no cat-predators in North America, which ended upon the arrival of the true cat, Pseudaelurus.[10][11]
Nimravids wouldn't reappear in North America until the appearance of Albanosmilus whitfordi and Barbourofelis around 12 Ma.[12][13]
