Chasmaporthetes, also known as hunting or running hyena, is an extinct genus of hyenas endemic to North America, Africa, and Asia during the Pliocene-Pleistocene epochs, living from 4.9 million to 780,000 years ago, existing for about 4.12 million years.
Its name means "he who saw the canyon", because it was the only one of its kind to cross the Bering land bridge.
