Hapalops is an extinct genus of ground sloth from the Early to Late Miocene of Brazil (Solimoes Formation), Bolivia (Honda Group), Colombia (Honda Group), and Argentina (Santa Cruz Formation) in South America. Though related to the giant Megatherium, Hapalops was much smaller, measuring about 1 metre (3.3 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.
