Palaeotherium
 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 is popularly 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.
