Phylogenetic Systematics of Peccaries (Tayassuidae: Artiodactyla) and a Classification of South American Tayassuids
Tayassuidae is a family of pig-like Artiodactyla restricted to the New World. Despite its rich fossil history, they have received less attention from a taxonomic and phylogenetic perspective whenExpand

Tayassu pecari (Link, 1795) (Mammalia, Cetartiodactyla): comments on its South American fossil record, taxonomy and paleobiogeography
Tayassu pecari is widely distributed across the Neotropical region, from northern Argentina to south-eastern Mexico. However, its fossil record is scarce; it is recorded since the middle PleistoceneExpand

Stable isotope signatures and the trophic diversification of akodontine rodents
Stable isotope analyses are frequently used to study trophic interactions, diet, and community processes, but they have seldom been applied to investigate the trophic niche structure of entireExpand

Skull morphology of the Brazilian shrew mouse Blarinomys breviceps (Akodontini; Sigmodontinae), with comparative notes on Akodontini rodents
Abstract Blarinomys breviceps is a shrew-like mouse, morphologically divergent from the remaining Akodontini (Cricetidae), and best known in the literature for its apparent fossorial adaptations.Expand

Morphometry of Catagonus stenocephalus (Lund in Reinhardt 1880) (Artiodactyla: Tayassuidae) and taxonomical considerations about Catagonus Ameghino 1904
Factors such as the discordance on the choice of characters by different authors and the fragmentary condition of the majority of fossils are responsible for many issues on the taxonomy of the SouthExpand

Isotopic paleoecology (δ13C) from mammals from IUIU/BA and paleoenvironmental reconstruction (δ13C, δ18O) for the Brazilian intertropical region through the late Pleistocene
Abstract Stable isotopes of carbon and oxygen of fossil specimens are widely used for paleoecological and paleoenvironmental inferences, and there has been an effort to better understand the isotopicExpand

Fossil peccaries of Late Pleistocene/Holocene (Cetartiodactyla, Tayassuidae) from underwater caves of Serra da Bodoquena (Mato Grosso do Sul State, Brazil)
Abstract New records of Catagonus stenocephalus and Tayassu pecari are reported from the karst of Serra da Bodoquena, located at a south-western portion of Brazil near the border with Paraguay. SkullExpand

Insectivory leads to functional convergence in a group of Neotropical rodents
The mandible of vertebrates serves as insertion area for masticatory muscles that originate on the skull, and its functional properties are subject to selective forces related to trophic ecology. TheExpand
On the Supposed Presence of Miocene Tayassuidae and Dromomerycinae (Mammalia, Cetartiodactyla) in South America
ABSTRACT The earliest record of North American mammals in South America is significant for constraining the timing of intercontinental faunal interchange. At present, the oldest securely datedExpand
