Tapiroidea is a superfamily of perissodactyls which includes the living tapirs and their extinct relatives. Tapiroids represent one of the oldest living lineages of large mammals. Their closest living relatives are rhinoceroses; the ancestral lineages of tapirs and rhinoceroses split from each other approximately 51–47 million years ago. Once a large group encompassing several families, tapiroids are today represented only by the four living species of the genus Tapirus. All living species are listed as endangered or vulnerable on the IUCN Red List.
