Abstract Present knowledge of Late Triassic tetrapod evolution, including the rise dinosaurs, relies heavily on fossil-rich continental deposits South America, their precise depositional histories and correlations. We report an extended succession Ischigualasto Formation exposed in Hoyada del Cerro Las Lajas (La Rioja, Argentina), where more than 100 fossils were newly collected, augmented by historical finds such as ornithosuchid Venaticosuchus rusconii putative ornithischian Pisanosaurus...
The Bauru Basin of SE Brazil is a large (ca. 370,000 km 2 ) Upper Cretaceous intracratonic feature, important for its fossil remains and particular value as source regional palaeoclimatic information. Historically, lithostratigraphic reconstructions have been performed mainly successions the central southern parts basin, resulting in scheme that not applicable to northernmost regions. In particular, northeastern deposits Marília Formation (Serra da Galga Ponte Alta members) reveal...
The dental anatomy of Candelariodon barberenai from the Dinodontosaurus Assemblage Zone (Pinheiros-Chiniquá Sequence, Santa Maria Supersequence, late Ladinian-early Carnian) south Brazil, is redescribed.Candelariodon was originally classified as Eucynodontia incertae sedis and our analysis recovered this taxon deeply nested within Probainognathia, sister Potheriodon plus Prozostrodontia.The lower postcanine dentition has several apomorphies shared with Prozostrodon, Santacruzgnathus,...
Uberabatitan ribeiroi is a Late Cretaceous titanosaur (Dinosauria, Sauropoda) from southeastern Brazil. Here we provide detailed revision of all its available specimens, including new elements the type-locality. One autopomorphy added to diagnosis taxon: astragalus with well-developed anteroposterior crest that mediodistally delimits tibial articulation. Linear regressions were conducted in an attempt circumscribe specimens within type-series, revealing it composed several individuals,...
Abstract Chiniquodontidae is a family of nonmammaliaform probainognathian cynodonts with occurrences in the Middle to Late Triassic Africa and South America (Brazil Argentina). The history marked by changes composition revisions due poor preservation first discovered specimens. Currently, includes two genera six species. Here, we apply computed tomography (CT-scan) method describe revise morphology one best-preserved chiniquodontid specimens (MCP 1600 PV, holotype ‘ Probelesodon ’ kitchingi...
Sacisaurus agudoensis is the only silesaurid known from Triassic beds of Santa Maria Supersequence and correlation its type locality to other deposits south Brazil has always been controversial.In an attempt improve this, a handful dinosaur cynodont remains found associated S. are here described compared.The anatomy sauropodomorph more similar that Norian forms such as Pantydraco caducus Unaysaurus tolentinoi than Carnian taxa Saturnalia tupiniquim Pampadromaeus barberenai .The cynodonts...
The Predebon Site, located in São João do Polêsine, Quarta Colônia region (Rio Grande Sul, Brazil) has a Triassic fauna, including footprints and traces of small vertebrates abundant remains rhynchosaurs. This fauna is typical the Hyperodapedon Assemblage Zone, which correlated to late Carnian Ischigualasto Formation (Ischigualasto-Villa Unión Basin) Argentina. present study records new fossil for Site collected 2001 that consists two dorsal sacral vertebrae referred same individual (MCN-PV...
Abstract Titanosaurs were successful herbivorous dinosaurs widely distributed in all continents during the Cretaceous, with major diversity South America. The success of titanosaurs was probably due to several physiological and ecological factors, addition a series morphological traits they achieved their evolutionary history. However, generalist nesting behaviour using different palaeoenvironments strategies key accomplish that success. Titanosaur sites have been found extensively around...
Actualmente se reconocen dos linajes de Kannemeyeriiformes (Synapsida, Dicynodontia) en la Formación Chañares del Ladiniano–Carniano (Cuenca Ischigualasto-Villa Unión, Argentina): stahleckériidos stahleckeriinos, basados postcráneos, y una sola especie no-stahleckeriinos, Dinodontosaurus brevirostris, conocida principalmente por material craneano. Los datos disponibles sobre mandíbula brevirostris basan el espécimen PULR-V 03, holotipo D. "platygnathus". Aquí presentamos un estudio...
The fossil record of the genus Bothrops is still sparse in South America. Most records belong to extant species recovered strata not older than late Pleistocene. was also tentatively reported from early Pliocene and early–middle Pleistocene Buenos Aires province, Argentina, based on fragmentary specimens. aim present contribution report partial vertebral column a viperid snake discovered lower layers Farola de Monte Hermoso locality, southern province. specimen can be referred Bothrops,...
