Hypsodonty in Pleistocene ground sloths was reported by Bargo et al. (2006), but no data was provided for megalonychids. Herein, hypsodonty indices (HI) are presented for 22 Megalonyx specimens (mean = 1.06, SD = 0.10), and statistical analysis suggests that there were no significant changes in HI during the ontogeny or phylogeny of the genus during the Pleistocene.
