A new pachyrukhine (Notoungulata: Typotheria) from the late Early Miocene of south-central Chile
Here, we studied several Pachyrukhinae (Mammalia: Notoungulata: Typotheria: Hegetotheriidae) fossils recovered from the late Early Miocene (Santacrucian SALMA) beds of the Cura-Mallín Formation at the Laguna del Laja (Biobío Region, Chile). The specimens

Paleobiological Integration of Santacrucian Sloths (Early Miocene of Patagonia) [PDF]
Ameghiniana, 2016 Abstract. Paleobiological integration proceeds from descriptive morphology and paleosynecological reconstruction. This integration is achieved through modeling of function, inference of faculties, performance and resource use to hypothesize about fundamental niche.

Geochronology of Type Santacrucian (Middle Tertiary) Land Mammal Age, Patagonia, Argentina
Journal of Geology, 1986 Mammal-bearing lacustrine and tuffaceous sediments from three localities of the Santa Cruz Formation, type fauna of the Santacrucian Land Mammal Age, in Patagonia, southern Argentina, are calibrated by radioisotope dating with the aid of magnetostratigraphy. The strata range from about 17.6 Ma to perhaps 16.0 Ma, and are thus of late-early Miocene age.

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 modern faunas.
