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 megalonychid 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.
