ABSTRACT Suspensory locomotion differs significantly from upright quadrupedal locomotion in mammals. Nevertheless, we know little concerning joint kinematics of suspensory movement. Here, we report three‐dimensional kinematic data during locomotion in brown‐throated three‐toed sloths (Bradypus variegatus). Individuals were recorded with four calibrated

An Enigmatic Nothrotheriinae (Xenarthra, Tardigrada) from the Pleistocene of Argentina
The aim of this contribution is to describe two femora (MACN Pv 14148 and MACN Pv 14149 ) recovered from the Pleistocene of Santa Fe Province Argentina, provided a taxonomic assignation for them, and to discuss some taxonomic and biogeographical aspects of these finds.

The Initial Opening of the Drake Passage Occurred During ca. 62‐59 Ma
Abstract Although the Drake Passage has been considered a critical component of ocean circulation and climate, its initial opening age remains controversial due to the weak constraints on the paleoposition of the Antarctic Peninsula. Here, new zircon U‐Pb geochronological studies are conducted on the Barchans Islands, providing a critical age ...

Read the free Plain Language Summary for this article on the Journal blog. Abstract Many endotherms from diverse taxonomic groups can respond to environmental changes through torpor, that is, by greatly reducing their energy expenditure for up to 24 hours (daily torpor) or longer (hibernation).

The sloths Scelidotheriinae (Xenarthra, Folivora): Taxonomy, biocronology, and biogeography [PDF]
Los perezosos Scelidotheriinae (Mammalia, Xenarthra, Mylodontidae) representan un clado sudamericano que, a pesar de tener una distribución geográfica muy amplia, no participaron del Gran Intercambio Biótico Americano (GIBA).

En el extremo sur de América del Sur, se han postulado varias áreas que podrían haber actuado como reservorio de taxones supérstites, especialmente en el lapso Mioceno-Pleistoceno tardío (“Araucanense”-Lujanense). Así, en el Pleistoceno tardío (ca.
