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, additional remains were described from Late Pleistocene aged deposits in Sistema Huautla, Oxaca, Mexico. It is considered closely related to Xibalbaonyx.[2]
