Megatherium americanum (late Pleistocene of South America) has traditionally been
regarded a herbivore, but its dietary habits have not been considered in terms of a …

The megatherioid sloths from the Santa Cruz Formation (Santacrucian Age; early-middle
Miocene, Patagonia, southernmost South America) occupy basal positions in the most …

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 …

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 tree sloths, Bradypus and Choloepus, show unusual masticatory specializations,
compared to each other and to other mammals. Both have an incomplete zygomatic arch …

This study investigates the biomechanics of dental function in Ptilodus (Multituberculata)
through vector analysis of masticatory muscles and comparisons of mechanically relevant …

Notoungulates, litopterns, and astrapotheres are among the most representative mammals
of the early Miocene Santacrucian Age. They comprise a diversity of biological types and …

Cranial musculature, dental function and mandibular movement patterns in Eremotherium
laurillardi were reconstructed from the examination of crania and dentitions. Size, shape and …

In this paper, the highly peculiar masticatory apparatus of glyptodonts is studied. The
general morphology of the skull is analysed using a morphometric procedure, the Resistant …

The masticatory apparatus of Pampatherium typum, P. humboldtii, and Holmesina
