A three‐dimensional geometric morphometric approach was employed to examine shape
variation in laser‐scan generated models of lower second molars and its relationship to diet …

The fossil xenarthrans include giant forms, the ground sloths (Tardigrada), characteristic of
the mammal fauna of the Pleistocene of South America. Although most authors agree in …

The goal of this research is to evaluate the relative strength of the influences of diet, size,
and phylogenetic signal on dental geometric shape. Accurate comprehension of these …

Cranial and temporomandibular joint (TMJ) form has been shown to reflect masticatory
forces and mandibular range of motion, which vary in relation to feeding strategy. Similarly …

Dental topographic analysis is the quantitative assessment of shape of three‐dimensional
models of tooth crowns and component features. Molar topographic curvature, relief, and …

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 …

Three orders of South American extinct native ungulates are recorded from the Santa Cruz
Formation along the Atlantic coast of Patagonia: Notoungulata (Adinotherium Ameghino …

Sloths are among the most characteristic elements of the Cainozoic of South America and
are represented, during the Pleistocene, by approximately nine genera of gigantic ground …

The Xenarthra includes the most intriguing mammals from the Cenozoic of South America:
the glyptodonts (Cingulata) and the ground sloths (Tardigrada). Their masticatory …

Three field seasons of exploration along the Río Alto Madre de Dios in Peruvian Amazonia
have yielded a fauna of micromammals from a new locality AMD-45, at∼ 12.8° S. So far we …
