The zebra-like Hipparion was long-legged and fast. And in most places, its comparison was the short-legged tubby hippo-rhino. From Texas to China to East Africa, hippo-rhinos like Chilotherium moved in great herds that left behind bone beds with tens of thousands of bones. They were true rhinos, close kin of today’s Rhinoceros, the Asiatic one-horned rhino.
