The first Brazilian Dinosaur Symposium The 1st Brazilian Dinosaur Symposium gathered paleontologists, geologists, and paleoartists in the city of Ituiutaba, Minas Gerais State, Brazil, from April 21st to 24th, 2013. The Dinosaur Symposium in the Pontal Campus of the Universidade Federal de ^ndia, Minas Gerais State, Brazil provided an opportunity to Uberla share many new results of dinosaur research being conducted around the world. The symposium coincided with a new dawn of scientific advances in dinosaur paleontology further expanding its importance, interest and credibility worldwide. The symposium gathered 177 participants and speakers from Brazil, Argentina, and United States. New discoveries were presented as well as discussions about the present and future of dinosaur research in areas that were once Gondwana
from the Triassic to the Cretaceous. Participants could attend a variety of short courses, including the history of paleontology, paleontology techniques, and novelties in paleoart and dinosaur taxonomy. Conferences by Matthew Lamanna, Max Langer, Fernando Novas, Michael Holz and Rodrigo Santucci, provided a wide view of the evolution, paleobiogeography and systematics of dinosaurs. The symposium was a unique opportunity to share the knowledge produced by over 12 research institutions in Brazil. This special volume includes papers on dinosaur paleobiology and, morphology, as well as paleoenvironments of South America (Fig. 1), presented at the 1st Dinosaur Symposium.

~es Ribeiro synthesize the evolution and Fernandes & Magalha paleoenvironments of the Bauru Basin, one of the most prolific Late Cretaceous dinosaur-bearing basins in Brazil, as well as its fossil occurrences. Bauru Basin's early paleontological research in the region of ^ngulo Mineiro (Minas Gerais state) is described and contextualTria ized by Peyerl et al., who describe the pioneer work carried out between 1906 and 1961. The biomechanics of the scapular girdle and forelimbs of the Late Triassic basal sauropodomorph, Unaysaurus tolentinoi, and its functional and ecological aspects are described and compared to Plateosaurus by Vargas-Peixoto and colleagues, shedding new light on its paleobiology and habits. A comprehensive and up to date listing of the Cretaceous South American sauropods was compiled by Farias et al., who also discuss the relation between sauropod diversity, sea level, and depositional environments. The authors also present the relative abundance and geographical distribution of diplodocimorphs and titanosaur in time, providing a great resource for sauropod researchers. polis (Uberaba, From the rich classic Brazilian outcrops of Peiro Minas Gerais state), Martinelli et al. describe the first titanosaur cranial bones and atlas. Cranial elements of titanosaurs are sparse and rare in Brazil, and this noteworthy contribution provides more elements for the understanding of the cranial anatomy of these dinosaurs. The prefrontal and squamosal closely resembles those of lithostrotian titanosaurs such as Rapetosaurus while the atlas seems to be more conservative. The Early Cretaceous S~ ao Domingos ichnological site in northern Tocantins state, Brazil, described in the 1980's, is analyzed by de Valais and colleagues. These tracks were considered by the authors as Parabrontopodus-like and related to basal sauropods, macronarians or diplodocoids, and represent the only vertebrate record from the Corda Formation. Gonz alez-Riga et al. discuss the dinosaur ichnites from the Agua del Choique section in Mendoza Province (Argentina), one of the most important track and footprint areas of South America. Hundreds of tracks of a diverse dinosaur fauna, including large titanosaurs and small theropods provide ichnological and anatomical information for Late Cretaceous paleoenvironments.

The dinosaur assemblages from northern Brazil and northern Africa are presented and compared by Candeiro, providing data about the distribution of saurischians and ornithischians in northern Gondwana and co-occurring taxa in both continents. Da-Rosa places all known Brazilian Triassic dinosaurian forms into a geological context, discussing the preservation types, facies subdivisions, and stratigraphic and tectonic implications. This Triassic fauna is subdivided into four assemblage zones, with dinosaur remains known to occur in three of them. Dinosaur occurrences from the Brazilian continental basins are briefly characterized and contextualized with paleoclimatic variations throughout the Mesozoic by Holz. This contribution discusses events of mini-ice ages to hothouse conditions in an updated overview of the Mesozoic. We would like to thank all the authors who participated in the 1st Brazilian Dinosaur Symposium, as well as those who contributed to the production of this volume. Our special thanks go to the Regional Editor, Reinhardt Fuck, and the Editor-in-Chief, James Kellogg who helped with the publication of this special issue of the Journal of South American Earth Sciences.
