Un Hegetotheriidae (Mammalia, Notoungulata) basal del Mioceno temprano de Patagonia
Revista Mexicana de Ciencias Geológicas, 2013 Hegetotheriidae constituye uno de los clados más derivados dentro del Orden Notoungulata. Ya diversificado en el Oligoceno tardío, sus representantes, muchos de aspecto gliriforme, son conspicuos componentes de las faunas de mamíferos terrestres ...

New Basal Interatheriidae (Typotheria, Notoungulata, Mammalia) from the Paleogene of Central Chile [PDF]
American Museum Novitates, 2006 Abstract Two new basal interatheriids (“notopithecines”) are described from central Chile. Specimens of a new taxon, Johnbell hatcheri, derive from Abanico Formation deposits near Termas del Flaco, in the valley of the Rio Tinguiririca, forming a distinctive element of the Tinguiririca Fauna.

An exceptionally well-preserved skeleton of Thomashuxleya externa (Mammalia, Notoungulata), from the Eocene of Patagonia, Argentina [PDF]
Palaeontologia Electronica, 2017 We describe one of the oldest notoungulate skeletons with associated craniodental and postcranial elements: Thomashuxleya externa (Isotemnidae) from Cañadón Vaca in Patagonia, Argentina (Vacan subage of the Casamayoran SALMA, middle Eocene). We provide body mass estimates given by different elements of the skeleton, describe the bone histology, and ...

Cranial Morphology of the Late Oligocene Patagonian Notohippid Rhynchippus equinus Ameghino, 1897 (Mammalia, Notoungulata) with Emphases in Basicranial and Auditory Region. [PDF]
PLoS ONE, 2016 "Notohippidae" is a probably paraphyletic family of medium sized notoungulates with complete dentition and early tendency to hypsodonty. They have been recorded from early Eocene to early Miocene, being particularly diverse by the late Oligocene ...

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.

Patagonian Eocene Archaeopithecidae Ameghino, 1897 (Notoungulata): systematic revision, phylogeny and biostratigraphy [PDF]
Journal of Paleontology, 2017 AbstractThe Archaeopithecidae is a very poorly known group of native ungulates from the Eocene of Patagonia (Argentina), whose alpha taxonomy has remained obscure since Ameghino’s times. It is traditionally considered as a family representative of the Casamayoran (middle Eocene) South American Land Mammal Age, and is thought to be morphologically close

Interatheriidae (Typotheria; Notoungulata), body size and paleoecology characterization [PDF]
Mammalian Biology, 2011 Abstract Size has a major influence on animal's adaptation to its environment and is central to paleobiological characterization of fossil mammals. We present new models of body mass estimation for the Interatheriidae (Notoungulata, Typotheria). This small herbivorous mammals extends from the late Paleocene to the late Miocene and they are very well ...

Systematics and stratigraphical range of the hegetotheriids Hegetotheriopsis sulcatus and Prohegetotherium sculptum (Mammalia: Notoungulata) [PDF]
Journal of Systematic Palaeontology, 2016 Hegetotheriidae is one of the most advanced clades within the endemic South American placental Order Notoungulata. The species Hegetotheriopsis sulcatus Kramarz & Paz, 2013 differs from all other known hegetotheriids in having a peculiar combination of cranial and dental features, some of them shared with Archaeohyracidae (sister group of ...
