“…The genus Aeolosaurus has been used to attribute CampanianeMaastrichtian to the Adamantina and Marília formations (Bertini et al, 1999;Santucci and Bertini, 2001), based on its Argentinian record. However, from the point of view of Martinelli et al (2011) and Filippi et al (2013), the evidence of this genus in the Bauru Basin is inconclusive. Certain specimens anteriorly identified as Aeolosaurus (Santucci and Bertini, 2001;Franco-Rosas et al, 2004;Marinho and Candeiro, 2005;Lopes and Buchmann, 2008;Santucci and Arruda Campos, 2011) have been assigned to Titanosauria (Martinelli et al, 2011) and Aeolosaurini indet (Martinelli et al, 2011;Filippi et al, 2013).…”

Considering that Aeolosaurini is recorded in Argentina from the lower Coniacian to Maastrichtian (Filippi et al, 2013), it is possible to assume that the Adamantina, Marília and Uberaba formations were deposited within this interval.…”

In addition, Machado et al (2013a, b) noted that Brasilotitan nemaphagus from the Adamantina Formation appears to be closely related to Antarctosaurus wichmannianus (Upper Cretaceous, Argentina) and Bonitasaura salgadoi (Santonian, Argentina), which might also indicate a Santonian age for at least a portion of the Adamantina Formation.…”

The aim of this research is to understand the tectonic setting of the Bauru Basin. This basin in centraleastern South America has been classified as intracratonic, but the basin-fill geometry, the involved subsidence mechanisms and the age of the deposits are poorly understood. In this work, the ranges of the fossil taxa are analyzed and ages are proposed for the lithostratigraphic units. Isopach maps were used to reconstruct the stratigraphic intervals of the basin fill. The stratigraphy of the Bauru Basin is compared with that of the adjacent basins, and the data are integrated with the available information on South American geodynamics. The fossil record indicates that sediment accumulated from the Cenomanian to early Paleocene, beginning after the Mochica Phase of the Andean orogeny. The basin-fill geometry demonstrates migration of the depocenter through time, which occurred simultaneously with migration of the Andean Basin and immediately after the orogenic events of the Peruvian Phase. We propose that the Bauru Basin is a component of a retroarc foreland system developed during the early stages of the Andean evolution and that it was developed in the back-bulge province of this system. The Andean Basin constitutes the foredeep depozone of this foreland system (including the Potosí, Oriente, Acre and Marañon basins). In addition, the Upper Cretaceous of the Parecis and Solimões basins were likely also developed in the back-bulge province. The thickness of the Bauru accumulation indicates that other mechanisms might have overlapped the flexural subsidence in this back-bulge province.

“…In addition, there is an isolate caudal vertebra of an Aeolosaurini indet. (Santucci and Bertini, 2001;Martinelli et al, 2011;Filippi et al, 2013) and several specimens of indeterminate titanosaurs (e.g., Campos and Kellner, 1999;Santucci and Bertini, 2001;Marinho and Candeiro, 2005). The specimens here described constitute the first cranial bones of titanosaurs from this region and unfortunately cannot be referred to any particular taxon rather than indeterminate lithostrotian titanosaurs.…”

The non-avian dinosaurs died out at the end of the Cretaceous, ~66 million years ago, after an asteroid impact. The prevailing hypothesis is that the effects of the impact suddenly killed the dinosaurs, but the poor fossil record of latest Cretaceous (Campanian-Maastrichtian) dinosaurs from outside Laurasia (and even more particularly, North America) makes it difficult to test specific extinction scenarios. Over the past few decades, a wealth of new discoveries from the Bauru Group of Brazil has revealed a unique window into the evolution of terminal Cretaceous dinosaurs from the southern continents. We review this record and demonstrate that there was a diversity of dinosaurs, of varying body sizes, diets, and ecological roles, that survived to the very end of the Cretaceous (Maastrichtian: 72-66 million years ago) in Brazil, including a core fauna of titanosaurian sauropods and abelisaurid and carcharodontosaurid theropods, along with a variety of small-to-mid-sized theropods. We argue that this pattern best fits the hypothesis that southern dinosaurs, like their northern counterparts, were still diversifying and occupying prominent roles in their ecosystems before the asteroid suddenly caused their extinction. However, this hypothesis remains to be tested with more refined paleontological and geochronological data, and we give suggestions for future work.
