Pachylemur insignis

Pachylemur insignis is one of the two known species of Pachylemur, an extinct giant lemur of Madagascar that was most closely related to the living ruffed lemurs and is sometimes called the giant ruffed lemur. It was more robust than the ruffed lemurs and up to three to four times larger. Its subfossil remains come mainly from central and south-western Madagascar. Dental wear shows it was a fruit specialist and an important seed disperser. It declined after humans reached Madagascar, probably through habitat loss, forest fragmentation and bushmeat hunting, and is thought to have died out between 680 and 960 CE. Some doubt remains whether it is distinct from Pachylemur jullyi.
