Puma incurva

Puma incurva was initially described in 1956 as an extinct subspecies of leopard under the name Panthera pardus incurva.^[2] It was generally accepted under that name until a review of the material in 2023 noted that, while certain features of the fossils were unusual for a leopard, they were much more similar to members of the genus Puma, and reassigned the subspecies to that genus as a full genus. It is hypothesized that P. incurva may have been the result of hybridization between Puma and Panthera (such as leopards). Material includes a nearly complete but badly crushed skull.^[1]

Puma incurva was a leopard-sized cat. The skull is mostly Puma-like, but the upper carnassial is Panthera-like.^[1]
