Paleobiological Integration of Santacrucian Sloths (Early Miocene of Patagonia) [PDF]

Ameghiniana, 2016
La integración paleobiológica procede desde la morfología hacia la reconstrucción paleosinecológica. Esta integración se produce a través de la modelización de la función, inferencia de facultades, desempeño y uso de los recursos para hipotetizar el ...

An Approach to the Biomechanics of the Masticatory Apparatus of Early Miocene (Santacrucian Age) South American Ungulates (Astrapotheria, Litopterna, and Notoungulata): Moment Arm Estimation Based on 3D Landmarks [PDF]

Journal of Mammalian Evolution, 2011
Notoungulates, litopterns, and astrapotheres are among the most representative mammals of the early Miocene Santacrucian Age. They comprise a diversity of biological types and sizes, from small forms, comparable to rodents, to giants with no analogues in

A singular Hegetotheriinae (Notoungulata, Typotheria) from the late Oligocene-Early Miocene of the Subandean Region of Bolivia

Brazilian Journal of Geology, 2021
Geological studies in the northern sector of the Chaco foreland Basin, Bolivia, yielded new fossils coming from late Oligocene-late Miocene of the Petaca Formation. Few fossil mammals were known from the Subandean Region of Bolivia. We report a partially

Paleosols and related soil-biota of the Early Miocene Santa Cruz Formation (Austral-Magallanes Basin, Argentina): a multidisciplinary approach to reconstructing ancient terrestrial landscapes

Latin American Journal of Sedimentology and Basin Analysis, 2021
The middle and upper parts of the lower Miocene Santa Cruz Formation (~17–15.9 Ma) in the southeastern Austral-Magallanes Basin (southern Patagonia, Argentina) crop out as a fluvial succession that in parts is pedogenically modified.
