Abstract As part of ongoing revisionary work on Antillean Megalonychidae, we document four new sloth species from Quaternary cave localities in Haiti and the Dominican Republic.* The new taxa and their tribal affiliations are as follows: Megalocnus zile (Megalocnini), Acratocnus ye (Acratocnini), and Neocnus dousman and N. toupiti (Cubanocnini). Significantly, each is closely related to species in genera long known from Cuba. This observation is of primary biogeographical importance because the… Expand
A New Genus of Megalonychid Sloth (Mammalia, Xenarthra) from the Late Pleistocene (Lujanian) of Sierra De Perija, Zulia State, Venezuela
TLDR
A cladistic analysis of the new taxon based on cranial characters indicates that it is closely related to Ahytherium, another late Pleistocene megalonychid from South America known from cranial remains, and suggests that there may have been at least two distinct clades within the family since the late Miocene. Expand
Intraspecific variation of Megalonychid sloths from Hispaniola and the taxonomic implications
TLDR
Results for Neocnus demonstrate the necessity for a reassessment of the current taxonomy and recognised characters, and the existence of two subspecies or an unrecognised new, northern paleo-island species. Expand
Premaxillae of the Extinct Megalonychid Sloths Acratocnus, Neocnus, and Megalonyx, and their Phylogenetic Implications (Mammalia, Xenarthra)
TLDR
Morphological evidence suggests that a broadened, plate-like premaxilla constitutes a synapomorphy for the entire clade Megalonychidae, and the loss of this process may unite late Miocene to Recent megalonychids. Expand
LATE OLIGOCENE MEGATHERIOIDEA FAUNA (MAMMALIA: XENARTHRA) FROM SALLA-LURIBAY (BOLIVIA): NEW DATA ON BASAL SLOTH RADIATION AND CINGULATA-TARDIGRADA SPLIT
TLDR
The existence of Pseudoglyptodon, four Orophodontidae and two Megalonychidae at the end of the Oligocene in South America is surprising and implies an early diversification of sloths and a Cingulata/Tardigrada split, probably before the Casamayoran, which would be in agreement with predictions based on molecular evidence. Expand
A peculiar climbing Megalonychidae from the Pleistocene of Peru and its implication for sloth history
TLDR
The discovery of D. nordenskioldi underscores the great adaptability of Tardigrada: an arboreally adapted form is now added to the already known terrestrial, subarboreal, and aquatic (marine and freshwater) fossil sloths. Expand
A New Genus of Megalonychid Ground Sloth (Mammalia, Xenarthra) from the Late Pleistocene of Quintana Roo, Mexico
TLDR
A new genus and species of late Pleistocene megalonychid sloth, Nohochichak xibalbahkah, is described from Hoyo Negro, a chamber in the Sac Actun cave system, Quintana Roo, Mexico, which indicates that the number of sloth taxa involved in the Great American Biotic Interchange is greater than previously understood. Expand
New Pleistocene remains of megalonychid ground sloths (Xenarthra: Pilosa) from the intertropical Brazilian region
TLDR
Comparisons of the mandible and ossicles are conducted with homologous elements of the contemporaneous and sympatric Ahytherium aureum Cartelle, De Iuliis, and Pujos, 2008, and reinforce the distinction between these two species detailed in their initial descriptions. Expand
Eucholoeops Ameghino, 1887 (Xenarthra, Tardigrada, Megalonychidae) from the Santa Cruz Formation, Argentine Patagonia: implications for the systematics of Santacrucian sloths
ABSTRACT New well-preserved remains of the megalonychid sloth Eucholoeops Ameghino, 1887 recovered under strict stratigraphic control from late Early Miocene Santa Cruz Formation (c. 19 to 14 Ma;Expand
The Megalonychidae (Xenarthra, Tardigrada) from the late Miocene of Entre Ríos Province, Argentina, with remarks on their systematics and biogeography ☆
Abstract Megalonychidae are known from the Deseadan of Argentina and Bolivia to the present, represented by the tree sloth Choloepus Illiger. The principal fossil records of this clade are those fromExpand
Xibalbaonyx oviceps, a new megalonychid ground sloth (Folivora, Xenarthra) from the Late Pleistocene of the Yucatán Peninsula, Mexico, and its paleobiogeographic significance
Here we describe a new genus and species of giant ground sloth, Xibalbaonyx oviceps (Megalonychidae, Xenarthra), from the drowned cave system of the northeastern Yucatán Peninsula. The specimen isExpand
