BODY MASS ESTIMATIONS IN LUJANIAN (LATE PLEISTOCENE-EARLY HOLOCENE OF SOUTH AMERICA) MAMMAL MEGAFAUNA

In this paper a data base is initiated, with the body mass estimations for a number of xenarthran and epitherian species of the Lujanian Land Mammal Age (late Pleis- tocene - early Holocene of South…

Hypsodonty in Pleistocene ground sloths

Among Tardigrada hypsodonty is apparently affected by diet, habitat and habit, and among mylodontids, morphologic and biomechanical analyses indicate that hypsidonty was unlikely to be due solely to feeding behavior, such as grazing.

LIMB BONE PROPORTIONS, STRENGTH AND DIGGING IN SOME LUJANIAN (LATE PLEISTOCENE-EARLY HOLOCENE) MYLODONTID GROUND SLOTHS (MAMMALIA, XENARTHRA)

Abstract The mylodontid ground sloths (Xenarthra, Tardigrada) are among the most intriguing components of the Lujanian (Late Pleistocene-Early Holocene) fauna of the Pampean region in South America.…

Muzzle of South American Pleistocene ground sloths (Xenarthra, Tardigrada)

Examining models of food intake by reconstructing the appearance and shape of the muzzle in five species of Pleistocene ground sloths using reconstructions of the nasal cartilages and facial muscles involved in food intake allowed making a conservative reconstruction of muzzle anatomy in fossil sloths.

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 and are particularly interesting for paleobiological studies due to their diversity, richness and quality of preservation of the specimens.

Muscular Reconstruction and Functional Morphology of the Forelimb of Early Miocene Sloths (Xenarthra, Folivora) of Patagonia

The reconstructed forelimb musculature was very well developed and resembles that of extant Pilosa (especially anteaters), although retaining the basic muscular configuration of generalized mammals, and provide support for proposed Santacrucian sloths as good climbing mammals, possibly arboreal or semiarboreal, being also capable diggers.

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 are…
