Save the Hyena

The Hyaenidae (pronounced /haɪˈɛnɨdiː/) is a mammalian family of order Carnivora. The Hyaenidae family, native to both African and Asian continents, consists of four living species, the Striped Hyena and Brown Hyena (genus Hyaena), the Spotted Hyena (genus Crocuta), and the Aardwolf (genus Proteles).

Hyenas seem to have originated 26 million years ago from arboreal ancestors bearing similarities to the modern Banded Palm Civet. Plioviverrops, one of the earliest hyenas, was a lithe civet-like creature that inhabited Eurasia 20-22 million years ago. Details from the middle ear and dental structure marked it as a primitive hyena. This genus proved successful, its descendants flourishing with more pointed jowls and racier legs, much as the Canidae had done in North America.

15 million years ago, dog-like hyenas flourished, with 30 different species being identified. Unlike some of their modern descendants, these hyenas were not specialized bone-crushers, but were more nimble, wolf-like animals. The dog-like hyenas had canid-like molars, allowing them to supplement their carnivorous diet with vegetation and invertebrates.
