Dicerorhinus sumatrensis

The Sumatran Rhinoceros, Dicerorhinus sumatrensis, is the smallest and most ancient of all living rhino species — a relic of the Pleistocene epoch. Once widespread across Southeast Asia, it now survives only in isolated forest pockets, making it one of the world’s most endangered large mammals.

Description

Sumatran Rhinoceros (Dicerorhinus sumatrensis) — The Sumatran Rhino is a shaggy, two-horned rhinoceros that inhabits dense tropical rainforests. It is the last surviving representative of the genus Dicerorhinus, closely resembling extinct woolly rhinos in body shape and hair coverage. Adults have a reddish-brown coat of coarse hair, prehensile upper lips for browsing, and a height of roughly 1.2–1.5 meters at the shoulder.

Fossil evidence shows that this species once ranged from the Himalayan foothills through Myanmar, Thailand, and the Malay Peninsula, to Borneo and Sumatra. Its populations began collapsing thousands of years ago due to climate shifts and human hunting pressure. Today, only a handful remain, mostly in Sumatra and possibly Borneo, under intensive conservation protection.

Hunt History

Humans have hunted Dicerorhinus sumatrensis since the Late Pleistocene, when it shared its range with early modern humans and other megafauna across tropical and subtropical Asia. Its slow speed, large size, and habit of frequenting forest edges and riverbanks made it a high-value but dangerous prey. Hunters likely used wooden and stone-tipped spears, ambush traps, and pitfall systems to bring down the animal. Rhino horns and bones were also collected for ritual purposes, a tradition that persisted into historical times.

Earliest Archaeological Evidence of Human Predation:

Lang Rongrien Cave, Southern Thailand – Late Pleistocene layers (~38,000–27,000 BP) yielded Dicerorhinus remains with cut marks and percussion fractures associated with human activity.

Niah Cave, Borneo – Rhinoceros bones found in association with Upper Paleolithic stone tools (~45,000 BP), suggesting butchery or scavenging by early humans.

Hang Hum Site, Northern Vietnam – Pleistocene faunal remains of Dicerorhinus alongside human artifacts (~20,000 BP) indicate exploitation of rhinoceroses for meat and materials.
