New Saber-Toothed Cat Records (Felidae: Machairodontinae) for the Pleistocene of Venezuela, and the Great American Biotic Interchange
ABSTRACT The Machairodontinae fossil record in South America is not very diverse. Until now, only the genus Smilodon (Smilodontini) has been reported, with likely a single species, S. populator. A
Late Pleistocene Cingulates (Mammalia: Xenarthra) from Mene De Inciarte Tar Pits, Sierra De Perijá, Western Venezuela
TLDR
The paleoecological aspects of the Mene de Inciarte Cingulata reflect a complex and heterogenic faunal community dominated mainly by savanna elements with some forest elements that could represent seasonally dry forest.
The last marine pelomedusoids (Testudines: Pleurodira): a new species of Bairdemys and the paleoecology of Stereogenyina
TLDR
A new Stereogenyina species is described, based on an almost complete skull from the middle Miocene Capadare Formation, of Venezuela, and it is proposed that stereogenyins were a marine radiation of podocnemidid turtles, as corroborated by previous studies of fossil eggs and limb morphology.
New dinosaur (Theropoda, stem-Averostra) from the earliest Jurassic of the La Quinta formation, Venezuelan Andes
TLDR
Data show that the sampled summer-wet equatorial belt, which yielded the new taxon, played a pivotal role in theropod evolution across the Triassic–Jurassic boundary, as well as suggesting an earliest Jurassic maximum age for the La Quinta Formation.
A NEW FOSSIL CANID ASSEMBLAGE FROM THE LATE PLEISTOCENE OF NORTHERN SOUTH AMERICA: THE CANIDS OF THE INCIARTE ASPHALT PIT (ZULIA, VENEZUELA), FOSSIL RECORD AND BIOGEOGRAPHY
Abstract Canids invaded South American during the Pliocene (2.8–3.1 Ma BP) as part of the Great American Biotic Interchange, but their record on the continent is relatively poor until the
A new Mourasuchus (Alligatoroidea, Caimaninae) from the late Miocene of Venezuela, the phylogeny of Caimaninae and considerations on the feeding habits of Mourasuchus
Mourasuchus (Alligatoroidea, Caimaninae) is one of the most peculiar crocodyliforms due to the skull morphology consisting of a long, wide, dorsoventrally flat rostrum with long, slender mandibular
A New Genus of Megalonychid Sloth (Mammalia, Xenarthra) from the Late Pleistocene (Lujanian) of Sierra De Perija, Zulia State, Venezuela
TLDR
A cladistic analysis of the new taxon based on cranial characters indicates that it is closely related to Ahytherium, another late Pleistocene megalonychid from South America known from cranial remains, and suggests that there may have been at least two distinct clades within the family since the late Miocene.
Review of the fossil matamata turtles: earliest well-dated record and hypotheses on the origin of their present geographical distribution
TLDR
New turtle remains from the early Miocene Castillo Formation, at Cerro la Cruz, northwestern Venezuela, are described and a paleobiogeographic hypothesis is proposed to explain its present geographic range.
