Ancient lineage of large felines potentially dates back approximately six million years, with Asia being the suspected starting point, as depicted in the illustration of Panthera blytheae.
Discovery of Ancient Big-Cat Fossil Sheds Light on Snow Leopard Evolution
In an exciting discovery, a team of scientists led by paleobiologist Jack Tseng unearthed the fossil of a big-cat skull during a fossil-seeking expedition on August 7, 2010. This significant find, reported online in the journal Proceedings of the Royal Society B, adds about two million years to the time when big cats branched out.
The fossil, named Panthera blytheae, was discovered in a bone bed in central Asia. This bone bed, where diverse species were well preserved in place, suggests a fluvial process, meaning bones were transported through a creek, river, or delta to accumulate in that spot.
The team carefully carved up the bone bed into smaller chunks to avoid damaging the fossils. Upon closer examination, the skull and jaws of the fossil were found to be remarkably similar to bones of today's cat species, particularly the snow leopard. This discovery supports a great stability in the adaptations of the snow leopard over millions of years.
Panthera blytheae is a significant find as it provides evidence to support the narrative of Asian origins for big cats. Big cats, including lions, tigers, and leopards, are known to have originated on the Tibetan Plateau. The divergence of big cats took place during the Late Miocene-Early Pliocene period.
The fossil discovery places the divergence of big cats squarely on the continent of Asia. The fossil discovered by Jack Tseng and his team is a sister to the modern snow leopard. This finding fills in a huge time gap and brings fossil and molecular data in line.
The discovery of P. blytheae inspires scientists to keep digging for more ancestral big-cat fossils in the Miocene rocks of central Asia. The fossil bed revealed a connection between Tibet's big cats, Tibetan antelopes, and blue sheep, forming an environmental refuge on the Tibetan Plateau. The Tibetan Plateau may have played a lead role in the rise of some of today's dominant predators, including big cats.
Studying the origins of big cats is important for predicting how today's lions, tigers, and leopards will respond to change. Jack Tseng, a Young Explorer grantee, hopes that this discovery will pave the way for further research into the evolutionary history of big cats and their interactions with their ancient environment.
