Dental occlusal surface area in relation to body mass, food habits and other biological features in fossil xenarthrans
Abstract. The Xenarthra includes the most intriguing mammals from the Cenozoic of South America: the glyptodonts (Cingulata) and the ground sloths (Tardigrada). Their masticatory apparatuses areExpand

Body mass estimation in Early Miocene native South American ungulates: a predictive equation based on 3D landmarks
South American native ungulates include extinct taxa that evolved within the geographical context given by the isolation of South America during most of the Cenozoic. The ungulates (ordersExpand

The Forelimb of Early Miocene Sloths (Mammalia, Xenarthra, Folivora): Morphometrics and Functional Implications for Substrate Preferences
Early Miocene sloths are represented by a diversity of forms ranging from 38 to 95 kg. Their forelimb bones differ in shape from those of their closest living relatives (less than 10 kg), BradypusExpand

Evaluating Habitats and Feeding Habits Through Ecomorphological Features in Glyptodonts (Mammalia, Xenarthra)
Abstract. The goal of this study is to evaluate ecomorphological variables in glyptodonts from different ages (Miocene to early Holocene), clades, and sizes, with the purpose of inferring theirExpand

On the Evolution of Large Size in Mammalian Herbivores of Cenozoic Faunas of Southern South America
One of the major features of the continental Cenozoic faunas of South America is the presence of native lineages of herbivorous mammals, and among them the largest representatives of each fauna. TheyExpand
