Asian Two Horned Rhino Skull Replica measures 16.5 inches. Asian Two Horned Rhino Skull Replica is museum quality polyurethane resin.

The Sumatran rhinoceros or Asian Two Horned Rhino is the smallest rhinoceros, although it is still a large mammal; it stands 3.67–4.76 ft. high at the shoulder, with a head-and-body length of 7.7 to 10.4 ft. and a tail of 14 to 28 in.

The Asian Two Horned Rhino are now critically endangered, with only five substantial populations in the wild: four in Sumatra and one in Borneo.

Ancestral rhinoceroses first diverged from other perissodactyls in the Early Eocene. Mitochondrial DNA comparison suggests the ancestors of modern rhinos split from the ancestors of Equidae around 50 million years ago.

The extant family, the Rhinocerotidae, first appeared in the Late Eocene in Eurasia, and the ancestors of the extant rhino species dispersed from Asia beginning in the Miocene.

Asian Two Horned Rhino is considered the least derived of the extant species, as it shares more traits with its Miocene ancestors.

Paleontological evidence in the fossil record dates the genus Dicerorhinus to the Early Miocene, 23–16 million years ago. Many fossils have been classified as members of Dicerorhinus, but no other recent species are in the genus.

Recent studies suggest that many specimens attributed to Dicerorhinus from the Pleistocene of China actually belong to Stephanorhinus, a closely related genus.

The earliest fossil record of the species is from the Early Pleistocene Liucheng Gigantopithecus Cave in Guangxi, China, which consists of a nearly complete mandible with preserved cheek teeth and various isolated teeth.

Fossil material of the Asian Two Horned Rhino also found in the Middle Pleistocene of Thailand.

Because of morphological similarities, the Asian Two Horned Rhino is believed to be closely related to the extinct woolly rhinoceros and Stephanorhinus.

Although some morphological studies questioned the relationship, recent molecular analysis has supported the close relationship.
