The living tree sloths Choloepus and Bradypus are the only remaining members of Folivora, a major xenarthran radiation that occupied a wide range of habitats in many parts of the western hemisphere during the Cenozoic, including both continents and the West Indies. Ancient DNA evidence has played only a minor role in folivoran systematics, as most sloths lived in places not conducive to genomic preservation. Here we utilize collagen sequence information, both separately and in combination with… 

The oldest known record of a ground sloth (Mammalia, Xenarthra, Folivora) from Hispaniola: evolutionary and paleobiogeographical implications

Abstract. Sloths were among the most diverse groups of land vertebrates that inhabited the Greater Antilles until their extinction in the middle-late Holocene following the arrival of humans to the

Early Oligocene chinchilloid caviomorphs from Puerto Rico and the initial rodent colonization of the West Indies

Dental remains from Lower Oligocene deposits of Puerto Rico attests to the presence of two distinct species of chinchilloid caviomorphs, closely related to dinomyids in a phylogenetic analysis, and thus of undisputable South American origin.

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.

Postcranial anatomy of the extinct terrestrial sloth Simomylodon uccasamamensis (Xenarthra, Mylodontidae) from the Pliocene of the Bolivian Altiplano, and its evolutionary implications

Extinct terrestrial sloths are common elements of the late Cenozoic South American fossil record. Among them, Mylodontinae species were particularly abundant in the Americas throughout the

Examining Natural History through the Lens of Palaeogenomics.

Integrative Approach Uncovers New Patterns of Ecomorphological Convergence in Slow Arboreal Xenarthrans

This work hypothesized that the morphology of Cyclopes is closer to ‘tree sloths’ than to anteaters, but yet distinct, entailing that slow arboreal xenarthrans evolved through ‘incomplete’ convergence, and quantified humeral and femoral convergence in slow arBoreal Xenarthrans.

The late Oligocene xenarthran fauna of Quebrada Fiera (Mendoza, Argentina) and its implications for sloth origins and the diversity of Palaeogene cingulates

The late Oligocene mammalian fauna of Quebrada Fiera is one of the most diverse of the Deseadan SALMA (South American Land Mammal Age). We describe its endemic xenarthran assemblage, represented by

The earliest record of Caribbean frogs: a fossil coquí from Puerto Rico

A distal humerus of a frog from the Oligocene of Puerto Rico is reported that represents the earliest known fossil frog from any Caribbean island and corroborates previous estimates suggesting that this diverse Caribbean lineage was present in the islands by the mid-Cenozoic.

A molecular phylogeny of two extinct sloths.

DNA was extracted and mitochondrial cytochrome b gene sequences were determined from representatives of two extinct groups of sloths, their two living relatives, anteaters and armadillos, to strengthen the view that the two families of living sloths adapted independently to an arboreal life-style.

Collagen Sequence Analysis of the Extinct Giant Ground Sloths Lestodon and Megatherium

Examination of phylogenetic potential of proteomics-based sequencing through the analysis of collagen extracted from two extinct giant ground sloths, Lestodon and Megatherium highlights that proteomics methods could yield plausible phylogenies that share similarities with other methods, but have the potential to be more useful in fossils beyond the limits of ancient DNA survival.

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.

The evolution of armadillos, anteaters and sloths depicted by nuclear and mitochondrial phylogenies: implications for the status of the enigmatic fossil Eurotamandua

Phylogenetic analyses confirm the order's monophyly and that of its three major lineages: armadillos, anteaters and sloths (‘Tardigrada’, renamed in ‘Folivora’), and results strongly support the grouping of hairy xenarthrans (anteaters and sloth) into Pilosa.

Phylogeny, Macroevolutionary Trends and Historical Biogeography of Sloths: Insights From a Bayesian Morphological Clock Analysis.

The phylogeny obtained supports the existence of the commonly recognized clades for the group and includes several recently described genera of sloths into an assembled morphological data supermatrix and applies Bayesian inference to 64 sloth genera.

Molecular phylogeny of the extinct ground sloth Mylodon darwinii.

Phylogenetic analyses using homologous sequences from all extant edentate groups suggest that Mylodon darwinii was more closely related to the two- toed than the three-toed sloths and, thus, that an arboreal life-style has evolved at least twice among sloths.

Evolutionary Relationships among Extinct and Extant Sloths: The Evidence of Mitogenomes and Retroviruses

A fully resolved and well-supported phylogeny is produced that supports dividing crown families into two major clades: 1) The three-toed sloth, Bradypus, and Nothrotheriidae and 2) Megalonychidae, including the two- toed sloths, Choloepus and Mylodontidae.

A mitogenomic timetree for Darwin’s enigmatic South American mammal Macrauchenia patachonica

An almost complete mitochondrial genome for the litoptern Macrauchenia is reported, showing that, when using strict criteria, extinct taxa marked by deep divergence times and a lack of close living relatives may still be amenable to palaeogenomic analysis through iterative mapping against more distant relatives.

Ancient proteins resolve the evolutionary history of Darwin’s South American ungulates

Proteomic analysis is applied to screen bone samples of the Late Quaternary South American native ungulate taxa Toxodon and Macrauchenia for phylogenetically informative protein sequences and the resulting consensus tree agrees well with recent higher-level mammalian phylogenies.
