Pachycrocuta was a genus of prehistoric hyenas. The largest and most well-researched species is Pachycrocuta brevirostris, colloquially known as the giant hyena as it is estimated to have averaged 110 kg (240 lb) in weight,[1] almost the size of a lioness or tigress, making it the largest known hyena. Pachycrocuta first appeared during the late Pliocene about 3 million years ago and went extinct during the middle Pleistocene, 400,000 years ago.


Fossil remains have been found broadly in Eurasia and southern and eastern Africa. Most material consists of fragmented remains, usually of the skull, but a cache of very comprehensive bone material was unearthed at the famous Zhoukoudian site, which probably represents the remains of animals using these caves as lairs for many millennia.[2] At the western end of their former range, at Venta Micena in southeastern Spain, a huge assemblage of Pleistocene fossils also represents a den.[3]

Pachycrocuta brevirostris skull

Other proposed species, P. robusta and P. pyrenaica, are less well researched; the former may simply be an exceptionally large European paleosubspecies of the brown hyena, Hyaena brunnea. Sometimes included in this genus (as Pachycrocuta bellax) is the extinct giant striped hyaena, Hyaena bellax.


It was probably a small-pack hunter of large animals (up to deer size and occasionally larger). Research by anthropologists Noel Boaz and Russell Ciochon on remains of Homo erectus unearthed alongside Pachycrocuta at the Zhoukoudian site attributed scoring and puncture patterns observed on hominin long bones and skulls—originally thought to be signs of cannibalism—to predation by Pachycrocuta.[4] Pachycrocuta may have also scavenged for food, probably preferentially so, because it was a heavyset animal not built for chasing prey over long distances. In this respect it would have differed from the spotted hyena of today, which is a more nimble animal that, contrary to its image as a scavenger, usually kills its own food but often gets displaced by lions. Apparently it was ecologically close enough to the smaller (but still large) relative Pliocrocuta perrieri that they are never found as contemporary fossils in the same region.
