Pogonodon

Pogonodon was have been similar in size to jaguars. Humerus measurements suggest P. platycopis had a humeral robustness greater than other nimravids, despite having shorter sabers than Hoplophoneus. == 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. 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. a 7 million year period with no cat-predators in North America, which ended upon the arrival of the true cat, Pseudaelurus. Nimravids wouldn't reappear in North America until the appearance of Albanosmilus whitfordi and Barbourofelis around 12 Ma. == References ==
