This chapter reviews the paleobiology of pilosans (anteaters and sloths) from the Santa Cruz
Formation, which comprise at least one genus of vermilinguan and 11 genera of sloths …

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 …

Xenarthrans stand out among mammals for various reasons, one of them being their
musculoskeletal postcranial specializations. Extant armadillos, anteaters, and sloths feature …

A paleobiological study of Santacrucian native ungulates is presented in this chapter. Seven
families are recorded: Hegetotheriidae, Interatheriidae, Toxodontidae, and …

The present work concerns xenarthrans from the collection of Santiago (Kaspar Jakob) Roth
(1850–1924) housed at the Palaeontological Institute and Museum of the University of …

The unique body plan of frogs (Lissamphibia: Anura) has been largely conserved from at
least 200 Myr, and its evolution from a more generalized tetrapod condition is still poorly …

Sloth morphological evolution has been widely studied qualitatively, with comparative
anatomy and morpho‐functional approaches, or through quantitative assessments of …

Rod monochromacy is a rare condition in vertebrates characterized by the absence of cone
photoreceptor cells. The resulting phenotype is colourblindness and low acuity vision in dim …

Identifying ecomorphological convergence examples is a central focus in evolutionary
biology. In xenarthrans, slow arboreality independently arose at least three times, in the two …

Early Miocene sloths are represented by a diversity of forms ranging from 38 to 95 kg, being
registered mainly from Santacrucian Age deposits in southern‐most shores of Patagonia …
