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. Tapiridae first appeared during the early Oligocene in Europe, and are thought to have originated from the tapiroid family Helaletidae.^[1]^[2]
