Hezheng Hipparion Beds, Gansu Province, China.  Early Miocene Epoch: 20-18 mya.  Skull measures 20" long, 12" wide, 15" high.  Only complete skull known to exist.  Agriotherium is from the family Hemicyonidae.  Hemicyonids were neither bears nor dogs but shared characteristics of both.  They were fast, very active hunters that ran on their toes like dogs.  This mode of stride is known as digitigrade- an animal that stands or walks on its toes.  Agriotherium may have been the largest terrestrial carnivore to have ever existed, measuring more that 10 feet in length and weighing over 2000 pounds.  This mammal was the apex predator of its time and had no equal.
