I'm very interested in the comparative morphology of the fossil lepidosaurians (lizards, snakes and sphenodontians) across the Mesozoic and Cenozoic eras. I also study the Neogene of Brazilian Amazonia, with emphasis in reptile faunas, age and temporal resolution of the Miocene of northern South America (Source: Lattes Curriculum)

The Cenozoic vertebrate fossil record in Brazil is extremely rich and diversified. Most of the fossils of the early Cenozoic are specifically concentrated in the Paleogene deposits located in the northeast as well as in the southeast parts of the country. On the other hand, deposits of Neogene Age are particularly concentrated in the southwest of the Brazilian Amazon region, mainly repres…
In Brazil, the Cretaceous and "Tertiary" fossil record of squamates is more conspicuous in the southeastern and northern parts of the country. This includes only lizards and snakes, representing a minor component of the known diversity for the entire South American Mesozoic-Cenozoic. The most fossilifeous Brazilian deposits of Cretaceous-"Tertiary" age are from the Bauru (Meso/NeoCretaceo…
The Acre Basin comprise the state of Acre and the Southern Amazonas, presenting a broad stratigraphic sequence, from the late Miocene of the Solimões Formation the most known and studied. The amniotes paleofauna from this geological unit has been well documented and studied since the late 19th century; however, the paleoichthyofauna records are still incipient, despite the rich fossil mat…
Testudines is a clade composed of two sister lineages, Cryptodira and Pleurodira, both with living and fossil representatives, and which differ mainly in the way the neck is retracted into the hull: vertically and laterally, respectively. Fossil testudines are quite common throughout the South American Cenozoic, since most fossils are represented by elements of the carapace and plastron, …
Clevosauridae (Lepidosauria, Rhynchocephalia) was a clade of Sphenodontia considerably abundant during the early Mesozoic. Clevosaurus represents the most diverse and broadly distributed genus among the group, with species ranging from the Upper Triassic to the Lower Jurassic. In the deposits of the Upper Triassic of South America (Rio Grande do Sul, Brazil), two species of Clevosaurus ar…
Knowing vertebral morphologic characteristics of serpents is essential to its anatomical, systematic and especially paleontological study. However, descriptions of the skeleton in some groups are rare or too superficial. This is the case of the Viperids. All observed and rarely reported differences are extremely sutil and require substantial descriptive refinement and discriminant analise…

Snakes constitute an ecologically and taxonomically diverse group of squamates, with more than 3000 living species distributed across all continents except Antarctica. In the past few decades several phylogenetic hypotheses have been proposed for snakes, both regarding their placement within Squamata and the details of their ingroup relationships. These hypotheses were initially based on …
Vertebrate fauna from Solimões Formation (upper Miocene) has been extensively studied. A rich fauna of mollusks (gastropods and bivalves), mammals, reptiles, birds and angiosperms trunks have been discovered in the past few decades. However, few of these studies aimed to understand taphonomic aspects of those fossil deposits. Geochemical investigations in biomineralized tissues have been …
