Hyainailouros

Hyainailouros ("hyena-cat") is an extinct polyphyletic genus of hyaenodont belonging to the family Hyainailouridae that lived during the early to middle Miocene, of which there were at least three species spread across Europe, Africa, and Asia.

Closely related to other large African hyaenodonts such as Simbakubwa and Megistotherium, Hyainailouros walked with a semi-digitigrade stance and was probably capable of large, leaping bounds.
