Crocuta dietrichi is an extinct species of hyena closely related to the modern spotted hyena. It lived through the Plio-Pleistocene, and has been reported from as early as 4.4 million years ago[1] to as recently as 1.7 million years ago.[2] It has been found in southern, eastern, and possibly northern Africa.[3] During the Pliocene Crocuta dietrichi coexisted with the larger Crocuta eturono in eastern Africa,[4] where niche partitioning had likely occurred between the two species, with Crocuta dietrichi acting as an opportunistic predator and scavenger while Crocuta eturono was a more specialized predator of large prey.[5] Crocuta dietrichi is the earliest known member of the genus Crocuta.[2][3]
Characteristics
[edit]Crocuta dietrichi was slightly smaller than the spotted hyena[5] but was otherwise morphologically very similar to the modern species.[6] Crocuta dietrichi was smaller than most Crocuta.[3] Relative to other members of its genus Crocuta dietrichi had a longer talonid on its first premolar, a shorter third premolar, and a wider fourth premolar.[3]
