Nycticebus linglom

Nycticebus linglom, written with a question mark in its original naming because its genus is uncertain, is a fossil strepsirrhine primate from the Miocene of Thailand. It is known only from a single tooth, an upper third molar catalogued as T Li 41, found at Li Mae Long in Lamphun province and dated to about 18 million years ago, in the latest Early Miocene. French paleontologists Pierre Mein and Léonard Ginsburg described it in 1997 and linked it most closely to the living slow lorises, but with so little material they only tentatively placed it in the genus Nycticebus. The tooth is tiny, 1.29 mm long and 1.82 mm wide, and Mein and Ginsburg called it the smallest known prosimian molar. It is triangular, with three low cusps and a single root, and it most resembles the molar of the Bengal slow loris. The specific name is the Thai word for loris.
