Systematics and evolutionary significance of the small Abrocomidae from the early Miocene of southern South America
According to these results, Abrocomidae might have been as diverse as its sister clade Octodontidae-Echimyidae during the late Oligocene–early Miocene, with extant abrocomids being currently restricted to late-diverged euhypsodont representatives.
First record of Banderomys leanzai Kramarz, 2005 (Rodentia, Caviomorpha) in Chubut Province, Patagonia (Argentina)
The aim of this work is to report the first record of B. leanzai outside the type locality; the new specimens come from the early Miocene of central Chubut Province (Patagonia, Argentina).
A New Chronology for Middle Eocene-Early Miocene South American Land Mammal Ages
Cenozoic South American Land Mam- mal Ages (SALMAs) have historically been correlated to the geologic time scale using 40 Ar/ 39 Ar dating and magnetostratigraphy. At Gran Barranca (68.7°W,
Cavioids, Chinchilloids, and Erethizontoids (Hystricognathi, Rodentia, Mammalia) of the Early Miocene Pampa Castillo Fauna, Chile
ABSTRACT Caviomorph rodents became important components of South American faunas after their Eocene arrival from Africa. Here we describe the cavioid, chinchilloid, and erethizontoid caviomorphs of
Abstract . Fossil rodents from the Rio Santa Cruz (RSC) classic localities (Santa Cruz Formation, Early–Middle Miocene) are known by the works of F. Ameghino and W.B. Scott since the end of the 19 th
Dental homologies and evolutionary transformations in Caviomorpha (Hystricognathi, Rodentia): new data from the Paleogene of Peruvian Amazonia
ABSTRACT Dental homologies and evolutionary transformations within caviomorph rodents have long been disputed. Here, we participate in these debates in providing new insights from the dental
Giant rodents from the Neotropics: diversity and dental variation of late Miocene neoepiblemid remains from Urumaco, Venezuela
Dental variation that indicates the presence of at least two giant rodent taxa in Urumaco is document and Quantitative analysis of dentition of the different neoepiblemid species supports the differentiation between Neoepiblema and Phoberomys and suggests that several recognized species of Phobermys could represent different ontogenetic stages of one or few taxa within the genus.
Phylogeny and Evolutionary Patterns of South American Octodontoid Rodents
The divergence of octodontoid families and subfamilies is estimated to have occurred during the Late Oligocene, which is consistent with molecular estimates, but older than previous inferences based on the fossil record.
New Middle Miocene Caviomorph Rodents from Quebrada Honda, Bolivia
The rodents of Quebrada Honda are more similar to those of Patagonia than those of northern South America, paralleling patterns seen in other mammal groups from this fauna.
Systematic Revision and Evolutionary History of Acarechimys Patterson in Kraglievich, 1965 (Rodentia, Caviomorpha, Octodontoidea)
Abstract. The octodontoid rodent Acarechimys was abundant during the early Miocene and had the widest temporal and geographic distribution of any extinct caviomorph. Despite this extensive fossil
