Abstract Two new specimens of the aquatic sloth Thalassocnus from the Pliocene of Peru are described, one of T. carolomartini McDonald and Muizon, 2002 and the other T. yaucensis, sp. nov. Comparisons with the type species of Thalassocnus, T. natans, demonstrates that T. carolomartini and T. yaucensis are more similar morphologically to each other than to other species of the genus and are more derived. For example, both have a more elongated rostrum (premaxillae and mandibular spout) and more… Expand
How many species of the aquatic sloth Thalassocnus (Xenarthra: Megatheriidae) were in Chile?: new evidences from the Bahía Inglesa Formation, with a reappraisal of their biochronological affinities
ABSTRACT. The aquatic sloth, Thalassocnus, is one of the most intriguing linage of mammal knew from the southern pacific coast of South America during the late Neogene. It was initially recognized inExpand
The Southernmost Occurrence of the Aquatic Sloth Thalassocnus (Mammalia, Tardigrada) in Two New Pliocene Localities in Chile
Abstract. Thalassocnus is a sloth (Mammalia, Tardigrada) adapted to an aquatic lifestyle. It was first described from the Neogene deposits of the Pisco Formation of Peru, from where most of theExpand
THE EVOLUTION OF FEEDING ADAPTATIONS OF THE AQUATIC SLOTH THALASSOCNUS
TLDR
A detailed comparison of the cranial and mandibular anatomy of these species indicates different feeding adaptations of Thalassocnus, represented by five species that lived along the coast of Peru from the late Miocene through the late Pliocene. Expand
A NEW GENUS AND SPECIES OF NOTHROTHERIID SLOTH (XENARTHRA, TARDIGRADA, NOTHROTHERIIDAE) FROM THE LATE MIOCENE (HUAYQUERIAN) OF PERU
TLDR
Sub- sequent analysis indicates that the nothrotheriine sloth from riverbank deposits of the Rio Acre region of Peru in western Amazonia was originally assigned to Nothropus priscus Burmeister, 1882 and that it belongs to a new genus and species. Expand
A reappraisal of the phylogeny of the Megatheria (Mammalia: Tardigrada), with an emphasis on the relationships of the Thalassocninae, the marine sloths
TLDR
It is found that Thalassocnus indeed belongs to Megatheria, but is clustered amongst Megatheriidae, the family that includes the large-size Megatherium. Expand
A new nothrotheriid xenarthran from the early Pliocene of Pomata‐Ayte (Bolivia): new insights into the caniniform–molariform transition in sloths
TLDR
A cladistic assessment of the available dental and postcranial evidence indicates that Aymaratherium is either sister taxon to Mionothropus or sister to the clade Nothrotheriini within Nothotheriinae, which further support the monophyly of both the Noth rotheriINAe and theNothroTheriini, as suggested previously by several authors.

A new species of Megalonychidae (Mammalia, Xenarthra) from the Quaternary of Poço Azul (Bahia, Brazil)
Abstract The new genus and species Ahytherium aureum (Mammalia, Xenarthra, Megalonychidae) from the Quaternary of Poco Azul (Bahia, Brazil) is described. It is the first Brazilian megalonychid knownExpand
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.

Osteology and Functional Morphology of the Forelimb of the Marine Sloth Thalassocnus (Mammalia, Tardigrada)
Thalassocnus is a genus of “ground sloths” known from Neogene deposits, for the great majority of specimens, of the Pisco Formation (Peru). Five species are recognized, their description beingExpand
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

TLDR
A marine nothrothere from the late Miocene Aguada de Lomas vertebrate horizon of the Pisco Formation of the southern coast of Peru and some characters indicate a continuous evolution from the oldest to the youngest species, preferring the hypothesis of a single Thalassocnus lineage. Expand
