Research overview: Panthera palaeosinensis and early big-cat evolution

This overview surveys Panthera palaeosinensis, an early pantherine from the Pliocene of China that has figured prominently in debates about the origins of big cats. Known from cranial and dental material, this species combines relatively primitive features with characteristics of the Panthera lineage, and it has variously been linked to the ancestry of tigers or to the base of the genus as a whole. The survey reviews its anatomy, its position in competing phylogenetic schemes, and how it relates to other early pantherines such as Panthera blytheae and Panthera zdanskyi. It discusses how a small number of key Asian fossils anchor reconstructions of when and where the great cats arose, and why Panthera palaeosinensis remains an important, if debated, piece of the big-cat origin story.
