Rhinos and tapirs are more closely related to each other than to horses. The separation of horses from other perissodactyls took place according to molecular genetic analysis in the Paleocene some 56 million years ago, while the rhinos and tapirs split off in the lower-middle Eocene, about 47 million years ago.
Brontotheriidae is a family of extinct mammals belonging to the order Perissodactyla, the order that includes horses, rhinoceroses, and tapirs.Superficially, they looked rather like rhinos with some developing bony nose horns, and were some of the earliest mammals to have evolved large body sizes of several tonnes.
Three perissodactyl species (clockwise from left): plains zebra (Equus quagga), Indian rhinoceros (Rhinoceros unicornis) and South American tapir (Tapirus terrestris) Perissodactyla is an order of placental mammals composed of odd-toed ungulates – hooved animals which bear weight on one or three of their five toes with the other toes either ...
Tapiroidea is a superfamily of perissodactyls which includes the modern tapirs and their extinct relatives. Taxonomically, they are placed in suborder Ceratomorpha along with the rhino superfamily, Rhinocerotoidea.The first members of Tapiroidea appeared during the Early Eocene, 55 million years ago, and were present in North America and Asia during the Eocene.

Another way rhinos protect their skin is by trading services with a bird; they befriend oxpeckers. These 8-inch-long birds have a wide bill, stiff tail, and sharp claws.
In fact, Scott said he came up with the idea for the scene based on a real-life video of a baboon attack on a group of tourists in a parking lot in South Africa, according to the film's press notes.
The 1.5-m-long beast was related to palaeotheres, and suspected to be the ancestor of modern tapirs and rhinoceroses.Physically, it would have looked very similar to modern tapirs, although it probably lacked the tapir's characteristic proboscis.
