Dental shape variation of Neogene Pachyrukhinae (Mammalia, Notoungulata, Hegetotheriidae): systematics and evolutionary implications for the late Miocene Paedotherium species
(Cambridge University Press, 2018-10)
Paedotherium was the last representative of the pachyrukhines (Notoungulata, Hegetotheriidae), a small rabbit- or caviomorph rodent-like clade, with hypsodont and simplified dentition. In contrast to the Pliocene Paedotherium ...
New light on the endemic South American pachyrukhine Paedotherium Burmeister, 1888 (Notoungulata, Hegetotheriidae): Taphonomic and paleohistological analysis
(Pergamon-Elsevier Science Ltd, 2017-01)
Paedotherium is a small notoungulate endemic of South America, very abundant in the Neogene assemblages of the Argentine Pampas. Numerous specimens of this taxon were recovered in the Arroyo Chasicó Formation (Late Miocene), ...
Morfometría de las paleocuevas de la "Fm." Chapadmalal y su asignación a Actenomys (Rodentia), Paedotherium (Notoungulata) y otros mamíferos fósiles hospedantesMorphometry of paleocaves at the Chapadmalal "Formation" assigned to fossorial rodent Actenomys sp. (Rodentia, Caviomorpha), Paedotherium (Notoungulata), and to other fossil mammals
(Unidad de Zoología y Ecología Animal, Instituto Argentino de Investigación de Las Zonas Aridas, Cricyt, Conicet, 2011-08)
En la “Formación” Chapadmalal, aflorante en las barrancas que se extienden desde Mar del Plata a Miramar, se diferencian paleocuevas que han sido asignadas al roedor fósil Actenomys sp. (Rodentia, Caviomorpha). La asignación ...
Systematic and morpho-geometric analyses of Pachyrukhinae (Mammalia, Hegetotheriidae) from the Huayquerías, Mendoza (Argentina): Biostratigraphic and evolutionary implications
(Society of Vertebrate Paleontology, 2018-05)
We give to know new remains of Pachyrukhinae (Hegetotheriidae) from the Huayquerías de San Carlos (Mendoza, Argentina). We identify Tremacyllus impressus, proposing T. subdiminutus a synonym name, and giving to know new ...

Paedotherium bonaerense (Notoungulata, Hegetotheriidae) as a Case Study
(Asociacion Paleontologica Argentina, 2014-10)
En la presente contribución se describen y analizan las características mineralógicas, geoquímicas y paleohistológicas presentes en hemimandíbulas de Paedotherium bonaerense (Ameghino) (Mammalia, Notoungulata, Hegetotheriidae), ...
A new Hypsodont Notoungulate (Hegetotheriidae, Pachyrukhinae) from the late Miocene of the Eastern Cordillera, Salta province, Northwest of ArgentinaUn nuevo Notungulado Hipsodonte (Hegetotheriidae, Pachyrukhinae) del Mioceno tardío de la Cordillera Oriental, provincia de Salta, Noroeste de Argentina
(Servicio Nacional de Geología y Minería, 2014-10)
Late Miocene fluvial strata of the Palo Pintado Formation are broadly exposed to the northwest of the town of Angastaco, Salta province, Northwest of Argentina. These strata accumulated in the extensional Angastaco Basin. ...
Deciduous dentition and eruption pattern in late Miocene Pachyrukhinae (Hegetotheriidae, Notoungulata) from La Pampa Province, Argentina
(Taylor & Francis, 2017-04)
The study of juvenile remains of Paedotherium Burmeister from Cerro Azul Formation (La Pampa Province, Argentina; late Miocene) is presented. Upper and lower deciduous dentition (or permanent molars supposed to be associated ...
Tracing the Paleobiology of Paedotherium and Tremacyllus (Pachyrukhinae, Notoungulata), the Latest Sciuromorph South American Native Ungulates – Part II: Orbital, Auditory, and Occipito-Cervical Regions
(Springer, 2021-06)
The caudal cranium and occipito-cervical region, although usually overlooked, are informative about the paleobiology of fossil mammals, allowing inquiry into vision and hearing abilities, as well as head and neck postures. ...
