New toxodontid (Notoungulata) from the Early Miocene of Mendoza, Argentina [PDF]

Paläontologische Zeitschrift, 2014
We describe a new toxodontid species, Nesodon taweretus sp. nov., from the Aisol Formation in Mendoza Province, central-west Argentina. Nesodon is a frequently found Toxodontidae, member of the Notoungulata, an extinct endemic group of Cenozoic South American mammals that are ecologically similar to current hoofed ungulates.
