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 sloths (Megatheriidae and Mylodontidae). A few contributions have described their masticatory apparatus, but almost no attention has been paid to the reconstruction of the muzzle, an important feature to consider in relation to food intake, and particularly relevant in sloths because of the edentulous nature of the… 

Gregariousness in the giant sloth Lestodon (Xenarthra): multi-proxy approach of a bonebed from the Last Maximum Glacial of Argentine Pampas

This record represents the first accurate evidence of gregariousness for this ground sloth, providing new data on a poorly-known behavior among extinct Folivora, as well as interpreting the origin of the assemblage and diverse paleobiological and paleoecological aspects.

Feeding mechanics and dietary implications in the fossil sloth Neocnus (Mammalia: Xenarthra: Megalonychidae) from haiti

Osteological characters related to feeding were examined, along with comparative estimations of bite force with the extant tree sloths, Bradypus and Choloepus, and their known dietary habits as a means to infer aspects of the paleodiet of Neocnus.

Grazing in a New Late Oligocene Mylodontid Sloth and a Mylodontid Radiation as a Component of the Eocene-Oligocene Faunal Turnover and the Early Spread of Grasslands/Savannas in South America

This relatively sudden sloth radiation was a significant component of the Eocene-Oligocene faunal turnover and was related to the development of more open habitats of post-Eocene South America.

Snout shape and masticatory apparatus of the rodent‐like mesotheriid ungulates (Notoungulata, Typotheria): exploring evolutionary trends in dietary strategies through ancestral reconstructions

Mesotheriidae were small to medium‐sized native South American ungulates. Mesotheriids radiated from the early Oligocene epoch to the early–middle Pleistocene, in two subfamilies: Trachytheriinae and

On Megatherium gallardoi (Mammalia, Xenarthra, Megatheriidae) and the Megatheriinae from the Ensenadan (lower to middle Pleistocene) of the Pampean region, Argentina

Based on the anatomical and comparative analysis, it is proposed that M. gallardoi is a valid species and M silenum should be considered nomen vanum because it lacks diagnostic features and corresponds undoubtedly to a juvenile individual.

Nouveaux paresseux terrestres (Mammalia, Xenarthra, Mylodontidae) du Néogène de l'Altiplano bolivien

ABSTRACT New ground sloths (Mammalia, Xenarthra, Mylodontidae) from the Neogene of the Bolivian Altiplano. Two new Mylodontinae (Xenarthra, Tardigrada, Mylodontoidea) from the Bolivian Altiplano are

Digital Cranial Endocasts of the Extinct Sloth Glossotherium robustum (Xenarthra, Mylodontidae) from the Late Pleistocene of Argentina: Description and Comparison with the Extant Sloths

This study, which represents the first exhaustive analysis of digital endocasts of a fossil sloth, reveals the importance of the application of new methodologies, such as CT scans, for elucidating the evolutionary history of this peculiar mammalian clade.

Sexual dimorphism in the fossil ground sloth Lestodon armatus (Xenarthra, Folivora)

Lower caniniforms from the late Pleistocene of Argentina, Uruguay, and Bolivia were studied and support the existence of sexual dimorphism in L. armatus, a family of ground sloths widely distributed in the South American fossil record.

Predominance of Orthal Masticatory Movements in the Early Miocene Eucholaeops (Mammalia, Xenarthra, Tardigrada, Megalonychidae) and Other Megatherioid Sloths

The analysis of the tooth wear facets, combined with the shape of the temporomandibular joint, the presence of a fused mandibular symphysis, and a well-developed temporalis muscle, indicates that the orthal component was predominant during mastication.

This paper tests the hypothesis that Megatherium americanum had morphological features that are better explained by its having had carnivorous habits rather than by solely herbivorous ones, and suggests the possibility that the animal could have manipulated large prey and cached large food pieces in a safer place.

The extinct species of large terrestrial Sloth, indicated by the above name, was first made known by portions of its fossil skeleton discovered by Charles Darwin, Esq., F. R. S., at Punta Alta,

Phylogenetic relationships among sloths (Mammalia, Xenarthra, Tardigrada): the craniodental evidence

The results imply that the split between the two extant sloth genera is ancient, dating back perhaps as much as 40 Myr, and that the similarities between these two taxa present one of the most dramatic examples of convergent evolution known among mammals.

Evidence for advanced carnivory in fossil armadillos (Mammalia: Xenarthra: Dasypodidae)

The features suggest that Macroeuphractus occupied an extreme position in the carnivorous-omnivorous feeding behavior of euphractines, and its large size indicates that it could have easily preyed on hare-sized vertebrates.


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.

Interpreting the diet of extinct ruminants: the case of a non-browsing giraffid

Quantitative analyses of the microscopic wear patterns on the molars reveal significant differences between three modern species from the three dietary groups and suggest that this extinct giraffid was a grazer, although it cannot rule out the possibility that it was an intermediate feeder.

Dietary adaptation of some extinct ruminants determined by premaxillary shape

This study applies methods to determine the dietary adaptations of extinct ungulates through analysis of premaxillary shapes to identify browsers, grazers, and mixed feeders.

New ontogenetic evidence on the septomaxilla ofTamandua andCholoepus (Mammalia, Xenarthra), with a reevaluation of the homology of the mammalian septomaxilla

It is concluded that the armadillo septomaxilla has two neomorphic components: a lamina palatina beneath the cartilaginous nasal floor and a processus intrafenestralis extending rostrally into the nasal fossa.

Tooth microwear and premaxillary shape of an archaic antelope

Tooth microwear shows that the extinct bovid Kipsigicerus labidotus from the Miocene of Fort Ternan in Kenya was most likely a grazing feeder, with mixed-feeder tendencies, while morphologically the premaxilla most closely resembles that of a mixed feeder.
