==Taxonomy== It is still unclear whether the genus evolved in [[Africa]] or [[Asia]], although the oldest known fossils are from Africa and dated to about 3.8 mya.<ref name=":0">{{cite journal |last1=Rao |first1=Huiyun |title=Palaeoproteomic analysis of Pleistocene cave hyenas from east Asia |journal=Scientific Reports |date=2020 |volume=10 |issue=1 |page=16674 |doi=10.1038/s41598-020-73542-x |pmid=33028848 |pmc=7541484 }}</ref> The earliest remains from Asia currently attributed to the genus is ''Crocuta honanensis'' from the Early Pleistocene of China dating to around 2.5-2.2 million years ago, but its relationship to the living spotted hyena is ambiguous.
