'''''Neocnus''''' is an extinct [[genus]] of [[ground sloth]], whose species ranged across [[Cuba]] and [[Hispaniola]] ([[Haiti]] and [[Dominican Republic]]). ''Neocnus'' would have resembled a typical ground sloth, though much smaller, with a longer tail and a broad trunk, as well as lissome limbs and long claws.

Neocnus is an extinct genus of ground sloth, whose species ranged across Cuba and Hispaniola (Haiti and Dominican Republic). Neocnus would have resembled a typical ground sloth, though much smaller, with a longer tail and a broad trunk, as well as lissome limbs and long claws. This sloth was known for having caudal vertebrae that were broad, a trait shared with other ground sloths, indicating that this animal, like the tamandua of today, likely used its tail to stand upright. The caniniform teeth of the Neocnus were large and triangular, and its skull was deep and had a large, sagittal crest which, when used with the deep mandible likely allowed strong exertion by the masticatory muscles.
The fossils of this sloth were found in Haitian cave deposits. They have been dated to as recently as 4391 BP, calibrated to c. 5000 BP.[2] It is theorized that this sloth, in common with other Antillean sloths, was killed off by humans seeking its pelt and meat. Neocnus is suspected of having been semi-arboreal.[3]
