}}Hapalops is an extinct genus of ground sloth from the Early to Late Miocene of Brazil (Solimões Formation), Bolivia (Honda Group), Colombia (Honda Group),[1] and Argentina (Santa Cruz Formation) in South America.[2] Though related to the giant Megatherium, Hapalops was much smaller, measuring about {{convert|1|m|ft}} in length. Like most extinct sloths it is categorized as a ground sloth, but it is believed that the smaller size of Hapalops allowed it to engage in some climbing behaviors.[3] DescriptionIt had a robust body, short skull and long limbs with large, curved claws. When it did visit the ground the animal probably walked on the knuckles of its forelimbs, like a gorilla. Hapalops had very few teeth with no incisors, the mandible included only four pairs of teeth.[4][5] {{clearleft}}References{{Portal|Neogene|Mammals|Paleontology|Prehistory of South America}}1. ^Croft, 2007, p.300 2. ^Hapalops at Fossilworks.org 3. ^White, J. 1993.
