Protictitherium was one of the genetically oldest genera of the hyenas and livedin Eurasia and Africa during the Miocene 18 to 8, possibly up to 7 million years ago. It can be classified in the subfamily Ictitheriinae , which no more recent representatives belong to.
The genus is considered to be one of the earliest within the hyena family, but is paraphyletic . Protictitherium had a physique that resembled that of today's civet cats in shape and size, and possibly lived partly as a climber on trees. It is likely that the animals mainly fed on insects or were omnivorous .
The species Protictitherium punicum , known among other things from layers 12 million years old from the Bled Dorah formation in Tunisia , was one of the first hyena representatives to migrate from Europe to Africa.
