Teleoceras is an extinct genus of grazing rhinoceros. It lived in North America and southwestern France during the Miocene epoch, which ended about 5.3 million years ago, through the early Pliocene epoch.[5]

Teleoceras had much shorter legs than modern rhinos, and a barrel chest, making its build more like that of a hippopotamus than a modern rhino. Like the hippo, it was probably also semi-aquatic. Teleoceras had a single small nasal horn.[6] It was a quite heavy animal, reaching 1.81 tons in weight.[7]

Teleoceras is the most common fossil in the Ashfall Fossil Beds of Nebraska. In fact, its remains were so numerous and concentrated that the building housing the greatest concentraion of Ashfall fossils is called the "Rhino Barn". Most of the skeletons are preserved in a nearly complete state. One extraordinary specimen includes the remains of a Teleoceras calf trying to suckle from its mother. This animal was featured in the episodes "Are Rhinos Dinos?" and "Dawn Of The Cats" of the Paleoworld series.
