Dinocerata ("terrible horned") is an extinct order of plant-eating, rhinoceros-like hoofed creatures famous for their paired horns and tusk-like canine teeth. The earliest dinoceratan, Prodinoceras, appeared in Asia during the Paleocene, but nearly all later types are from North America (dinoceratans must have crossed the Bering land bridge, which may have been exposed during Paleocene-Eocene times). Dinoceratans lived alongside another group of large Eocene plant-eaters, the brontotheres.

Palaeotherium
phylum | Chordata | Palaeotherium is popularly reconstructed as a tapir-like animal but recent reexaminations of the skulls show that the nasal cavity was not designed to support a small trunk, thus starting a recent trend to reconstruct them as looking more horse-like. Recent anatomical studies also suggest that Palaeotherium, along with other palaeothere genera such as Hyracotherium, were closely related to horses.
