Patterns of morphological variation of extant sloth skulls and their implication for future conservation efforts
Several studies have shown an increased morphological variability of sloths from
mammalian norms, affecting varied phenotypic traits from skeletal parts to soft tissues. We …

3D finite element analysis and geometric morphometrics of sloths (Xenarthra, Folivora) mandibles show insights on the dietary specializations of fossil taxa
Sloths are represented today only by two distantly-related small, arboreal, and folivorous
genera. However, the fossil record of the clade is composed of many more taxa, with much …
