Femoral neck anteversion in Xenarthra
The FASEB Journal, 2022Degree of femoral neck anteversion distinguishes extinct sloth genera from each other, particularly when analyzed in combination with femoral neck angle. These data have been previously analyzed using a comparative sample including only extant sloths, which limits functional interpretations.

Paleogene Xenarthra and the evolution of South American mammals [PDF]
Journal of Mammalogy, 2015 Recent studies show Xenarthra to be even more isolated systematically from other placental mammals than traditionally thought. The group not only represents 1 of 4 primary placental clades, but proposed links to other fossorial mammal taxa (e.g., Pholidota, Palaeanodonta) have been contradicted.

Armadillos, anteaters, and sloths (Xenarthra)
2009Abstract Despite their heterogeneous morphologies, armadillos (Cingulata), anteaters (Vermilingua), and sloths (Folivora) form a monophyletic group of curious placental mammals, the Order Xenarthra. Indeed, all living and extinct members share the presence of supplementary intervertebral articulations termed “xenarthrales” in the ...

Morphology of the tongue of Vermilingua (Xenarthra: Pilosa) and evolutionary considerations
Journal of Morphology, 2017AbstractThe tongue of anteaters (Xenarthra, Pilosa, Vermilingua) is a highly specialized for myrmecophagy. Here, we describe the topography and histology of the tongue, and compare it to that of other xenarthrans and other myrmecophagous eutherian mammals. The tongue of Vermilingua is long and slender, with an apical protuberance, which differs between

The evolution of hyoid apparatus in Xenarthra (Mammalia: Eutheria)
Historical Biology, 2016AbstractThe hyoid apparatus reflects aspects of the form and function of feeding in living and extinct organisms and, despite the availability of information about this structure for Xenarthra, it remains little explored from an evolutionary perspective.

Evolutionary trends of the histological pattern in the teeth of Edentata (Xenarthra)
Archives of Oral Biology, 1985In a comparative study of the dental structure of Edentata, the central tissue was identified as a modified orthodentine, except in the Glyptodontidae where an osteodentine was found. Some evolutionary trends of the tissues in these teeth may have been related with the extinction of ground sloths.
