[21] Joshua Brookes considered the Sumatran rhinoceros, with its two horns, a distinct genus from the one-horned Rhinoceros, and gave it the name Didermocerus in 1828. A slight genetic difference is noted between the Western Sumatran and Bornean rhinos. These licks can be small hot springs, seepages of salty water, or mud-volcanoes.

[19] The channel between Sumatra and Malaysia was not as significant a barrier for the rhinos as the Barisan Mountains along the length of Sumatra, for rhinos in eastern Sumatra and Peninsular Malaysia are more closely related than the rhinos on the other side of the mountains in western Sumatra.

This traditional style of weaving, first developed for royal residences more than two centuries ago, is revered for its textural quality, durability and excellent pattern clarity. "Description of a new subspecies of Rhinoceros, from Borneo, "Malaysia's last male Sumatran rhino dies". [4], Ancestral rhinoceroses first diverged from other perissodactyls in the Early Eocene.
