Palaeotherium ('old beast') is an extinct genus of primitive perissodactyl ungulate. George Cuvier originally described them as being a kind of tapir, and as such, Palaeotherium ispopularly reconstructed as a tapir-like animal. 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 thatPalaeotherium, along with other palaeothere genera such as Hyracotherium, were closely related to horses.
The average species of Palaeotherium was about 75 cm (2 ft 6 in) tall at the shoulder and lived in the tropical forests covering Europe around 45 million years ago, during the early to midEocene.[1] The largest species, P. magnum of Mid Eocene France, grew to be almost as large as a horse.
