Meizonyx is an extinct genus of megalonychid ground sloth from the Pleistocene of El Salvador and southern Mexico. The type and only species, Meizonyx salvadorensis, was described in 1985 from a mandible found in Barranca del Sisimico and other remains found at Rio Tomayate in El Salvador considered to be Middle Pleistocene in age.[1] Later, in 2021, two partial skeletons were described from Late Pleistocene aged deposits in Sistema Huautla cave in, Oxaca, Mexico, with one of these dating to around 12,562 ± 130 years Before Present. It is considered closely related to Xibalbaonyx.[2] It is thought to be comparable or somewhat greater in size than Megalonyx jeffersonii. It inhabited relatively mountainous areas.[3]
