The record of South-American Pleistocene Megalonychidae is scarce. Of the species described for intertropical Brazil, including Megalonyx sp., Ocnopus gracilis, Valgipes deformis, Xenocnus cearensis and Ahytherium aureum, only the last, recently described, is new megalonychid species described here was recovered from the same locality as by: The aim of this work is the study the masticatory apparatus of the large Pleistocene ground sloths Glossotherium robustum, Lestodon armatus, Mylodon darwini and Scelidotherium leptocephalum. A systematic review of the Megatheriinae (Mammalia: BARGO ET AL.—HYPSODONTY IN PLEISTOCENE GROUND SLOTHS This chapter reviews the basic principles of ecomorphology and provides many. The giant megatheriine ground sloth Eremotherium eomigrans is described based on remains from the late Blancan to early Irvingtonian (late Pliocene to early Pleistocene) of Florida. It resembles the other giant megatheriines E. laurillardi and Megatherium americanum in size, but is clearly distinguished by a pentadactyl manus. It is assigned to the genus Eremotherium based on two Cited by:

Scelidodon piauiense nov. sp., a new Mylodontidae Scelidotherinae (Mammalia, Xenarthra) of the Quaternary of the Serra da Capivara National Park region (Piaui, Brazil). The skull, mandible and postcranial skeleton of a new species of Scelidodon, S. piauiense nov. sp., were discovered in in the Toca do Barrigudo, Serra da Capivara National Park Region, southeastern Piauí, by:   Abstract. Quaternary Scelidotheriinae (Mammalia, Xenarthra, Mylodontidae) are represented by three genera: Scelidotherium Owen, Valgipes Gervais, and Catonyx Ameghino. The genus Catonyx includes three species of ground sloths: C. cuvieri (Lund), C. tarijensis (Gervais and Ameghino), and C. chiliensis (Lydekker).Catonyx tarijensis and C. chiliensis were present during the Cited by: 3. An articulated skeleton of Thalassocnus natans (Xenarthra: Nothrotheriidae) and a review of some other fossil sloths provide new information on sesamoid bones located at the knee joint. A sesamoid bone and an ossified meniscus have been identified at this joint. The cyamo-fabella (posterior sesamoid of the tibio-femoral articulation) of T. natans may act like a pulley through which the tendon Cited by: A revision of Peruvian Xenarthra and the discovery of new specimens have increased our knowledge of the Order in this country. About thirty sites from three geographic regions, Amazonian Forest, the Andes, and the coast have yielded Xenarthra in Peru. The only well known Pre-Pleistocene Xenarthra is Thalassocnus from the Mio-Pliocene of the Pisco by:

sloths (e.g., Gaudin ; Pujos et al. c; press). Suspensory sloths are relatively small compared to fossil sloths, slow-moving mammals utilizing a mainly sus-pensory posture in arboreal environments of the tropical rainforests of South and Central America and some Antillean islands. It is generally suspected that the very pecu-File Size: 1MB.   In , Owen established a number of genera from the fossil specimens brought back by Darwin from South America. The first mylodontid, Glossotherium, was based upon a fragment of the left temporal region of the skull (NHM ), but Owen only created the genus and failed to designate a attempted to rectify this situation in , stating that the original temporal fragment Cited by: recovered, Lund noted three ground sloth species including M. bucklandi, which he based on a right dentary with m4 (ZMUC ) and described as being about the size of a tapir.   Burrowing armadillos, ground sloths and pampatheres might have been pre-adapted to the low-light conditions underground. Additionally, as xenarthrans are frequently the victims of vehicular collisions [ 17 ], awareness of their degenerate vision should aid in their by:
