Geographical Distribution of the Dinosaurs From Bauru Basin (Upper Cretaceous)

The Bauru Basin (Bauru and Caiuá basins) dinosaur fauna is diverse and typical from the Gondwana, specially composed hy Titanosauria and Abelisauridae. The dinosaurs are mainly found in rocks of the Adamantina and Marília formations (Bauru Group). Those specimens are represented by fragmentary remains deposited in an fluvio­lacustrine environment. The Bauru Group dinosaurs are similar to those found in Argentina. This composition suggests that there was a common assemblage during the Late Cretaceous in these regions. That fauna of dinosaurs share similarities to India and Madagascar specimens, reflecting a common Gondwanan origin.
