Intracranial Anatomy of Oxyodontherium zeballosi (Litopterna, Macraucheniidae) from the Río Quinto Formation, San Luis Province, Argentina

Historical Biology
Utilising segmental data of MHIN-UNSL-GEO-V 465, we extend and re-evaluate previous observations on the morphology of the macraucheniid Oxyodontherium zeballosi comparing with additional micro and medical CT evidence from published data on Litopterna and other South American Native Ungulates (SANU).

Litopterna (Mammalia) from the Santa Cruz Formation (Early-Middle Miocene), Río Chalía, Patagonia, Argentina

Andean Geology
The southern margin of the Río Chalía valley (also known as Sehuen or Shehuen), Province of Santa Cruz, Argentina, offers excellent outcrops of the Early-Middle Miocene Santa Cruz Formation (SCF). However, the information about the faunal content of these levels is scarce due to insufficient prospection.
