Hapalops, a smaller-sized and early sloth of the Megatheroidea, appeared in the middle
Miocene Santa Cruz formation of Argentina. This genus is part of the group from which later …

The megatherioid sloths from the Santa Cruz Formation (Santacrucian Age; early-middle

In this work, we describe postcranial elements of Mylodon listai distributed in collections
from Argentina, Chile and Europe. Mylodon listai remains from Patagonia are clearly …

Since its original description nearly two hundred years ago, the late Pleistocene

The Pampa Castillo site in southern Chile has yielded a wide variety of Early Miocene

This chapter reviews the paleobiology of pilosans (anteaters and sloths) from the Santa Cruz

This study comprises a comparative description of the skull anatomy in the basal
megatherioid sloth Schismotherium fractum, based on specimens from the Santa Cruz …

The fossil record of megatheriine ground sloths extends back to the middle Miocene, but
only Pleistocene megatheriines are reasonably well understood. The taxonomy of pre …
