More than half a century ago, Percy Butler touted the importance of analyzing teeth to
understand their function in an evolutionary context. There have been many advances in the …

The living tree sloths Choloepus and Bradypus are the only remaining members of Folivora,
a major xenarthran radiation that occupied a wide range of habitats in many parts of the …

The first sloth coprolites were collected at the end of the Nineteenth Century at Cueva de
Milodón in Chile. There are 23 localities in North and South America and the West Indies …

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 …

Over 40 years ago, Clifford Jolly noted different ways in which Hadropithecus stenognathus
converged in its craniodental anatomy with basal hominins and with geladas. The Malagasy …

Based on data from analyses on previously-reported carbon stable isotope data from dental
enamel and dentine from tusks reported in the literature, diets were inferred for the …

The earliest euprimates to arrive in North America were larger‐bodied notharctids and
smaller‐bodied omomyids. Through the Eocene, notharctids generally continued to increase …

The morphological and ecological diversity of lemurs and lorisiformes once rivaled that of
the rest of the primate order. Here, we assemble a dataset of 3D models representing the …

Fossil sloths are regarded as obligate herbivores for reasons including peculiarities of their
craniodental morphology and that all living sloths feed exclusively on plants. We challenge …

The evolution of increased tooth crown height is considered to be an adaptation for coping
with excessive rates of dental wear associated with abrasive herbivorous diets, such as …
