Chinchillidae and Dolichotinae rodents (Rodentia: Hystricognathi: Caviomorpha) from the late Pleistocene of Southern Brazil
(Sociedade Brasileira de Paleontologia, 2011-12)
New records of rodents from the late Pleistocene Chuí Creek, Rio Grande do Sul State, southern Brazil, are here described. A partial dentary with fragmented cheek teeth is identified as Chinchillidae, Lagostomus Brookes ...
Paleobiology of the basal hydrochoerine Cardiomys Ameghino, 1885 (Rodentia, Caviomorpha, late Miocene, South America) as inferred from its postcranial anatomy
(Paleontological Society, 2018-09)
Extinct Hydrochoerinae traditionally included within 'Cardiomyinae' (Cavioidea, Caviidae) are caviomorph rodents well represented in the late Miocene to late Pliocene of Argentina, but their paleobiology has received little ...
Deep changes in masticatory patterns and masseteric musculature configurations accompanied the eco-morphological evolution of cavioid rodents (Hystricognathi, Caviomorpha)
(Elsevier Gmbh, 2019-05)
Cavioids are one of the most eco-morphologically divergent clades among South American caviomorph rodents. In an unique way, they display three mandibular morpho-types which are linked to the relative positions and relations ...
Diversity, phylogeny and biogeography of the South American ‘cardiomyine’ rodents (Hystricognathi, Cavioidea) with a description of two new species
(Palaeontological Association, 2018-02)
‘Cardiomyine’ rodents are extinct large terrestrial Caviidae closely related to capybaras, that inhabited large parts of South America during the middle Miocene and Pliocene. They are mostly preserved as isolated teeth, ...
Small mammal diversity in Semi-deciduous Seasonal Forest of the southernmost Brazilian Pampa: the importance of owl pellets for rapid inventories in human-changing ecosystems
(Universidade de São Paulo, 2020-06)
The Pampa biogeographic province covers a mere 2% of the Brazilian territory (176,496 km2). However, it stands out as a complex and diverse ecosystem, although its mammal communities are still scarcely understood. Human ...
Palimpsest of micromammal deposits in an archaeological rock shelter (Álvarez 4, Late Holocene) from northwestern Patagonia, Argentina
(Springer, 2021-10)
This study provides a taphonomic and paleoenvironmental analysis of the micromammal (˂1 kg) accumulations from the archaeological site Álvarez 4 (AZ4), a rock shelter located at the middle basin of the Limay River, Río ...
Holocene small mammals hunted by owls and humans in southern Brazil: taphonomic evidence and biological significance
(Wiley Blackwell Publishing, Inc, 2019-05)
Understanding resource utilization and economic diversification among Holocene hunter-gatherers in southern Brazil requires in-depth taphonomic analysis of faunal assemblages. Three Early to Late Holocene archaeological ...
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 ...
Late Miocene mammals from the Calchaquí Valley (Palo Pintado Formation, northwestern Argentina): Biogeographic and paleoenvironmental implications for the southern central Andes
(Pergamon-Elsevier Science Ltd, 2021-12)
With noteworthy outcrops in the Angastaco Basin (Salta Province), the Palo Pintado Formation is perhaps one of the most intensely studied late Miocene stratigraphical unit of northwestern Argentina from geological, ...
