Abstract
Multiple large cat tracks were found within Chilly Bowl Cave, Arkansas, representing at least two individuals of the genus Panthera. Large felid bone fragments were also found in a passageway near the tracks. These poorly preserved skeletal remains primarily consist of metapodials and phalanges and represent the North American Pleistocene jaguar, Panthera onca. Fusion of metapodial epiphyses indicate adult foot size had been reached for this large jaguar. One set of tracks is also consistent with the size and morphology of P. onca. The other tracks are much larger than is known for extant or prehistoric jaguars, and are here attributed to Panthera atrox, the American lion. An alternate hypothesis for the smaller tracks is that they could represent a younger P. atrox instead of P. onca. Regardless of the inability to identify the smaller feline prints to species, these remains and tracks from Chilly Bowl Cave record cave utilization by two separate Pleistocene felids, interpreted here as jaguar and American lion.
