Paleoecology of the mammalian predator guild of Southern Patagonia during the latest Pleistocene: Ecomorphology, stable isotopes, and taphonomy [PDF]

open access: yes, 2013
During the late Pleistocene, Patagonia had a rich fauna of large mammals including some megamammals such as ground sloths (Mylodon darwini), horse (Hippidion saldiasi), and camelids (e.g., Lama guanicoe).

New evidence on the filogenetic relationship betwen South and North American Pleistocene bears [PDF]

open access: yes, 2012
The subfamily Tremarctinae (Ursidae: Camivora), distributed exclusively in America, comprises five genera: Plionarctos from the upper Pliocene of North America, Arctodus, that groups the two North American species; Arctotherium and Pararctotherium with ...

Paleoecology of the large carnivore guild from the late Pleistocene of Argentina [PDF]

open access: yes, 2006
The paleoecology of the South American fossil carnivores has not been as well studied as that of their northern relatives. One decade ago Fariña suggested that the fauna of Río Luján locality (Argentina, late Pleistocene–early Holocene) is not balanced ...

A Blancan (Pliocene) short-faced bear from El Salvador and its implications for Tremarctines in South America

open access: yes, 2012
We present here a deciduous tooth recovered from the Blancan (Pliocene) Río Tomayate locality (Republic of El Salvador) and assign it to cf. Arctotherium (South American short-faced bears) based on its morphology and size.

Elbow Joint Geometry in Bears (Ursidae, Carnivora): a Tool to Infer Paleobiology and Functional Adaptations of Quaternary Fossils [PDF]

open access: yes, 2017
Bears are currently represented by eight species among Carnivora. Being all particularly large and generally plantigrade limits to certain extent their functional morphology so that inferences about their past diversification are difficult to achieve. We

The fossil record of the short-faced bears (Ursidae, Tremarctinae) from Venezuela. Systematic, biogeographic, and paleoecological implications [PDF]

open access: yes, 2007
