Abstract
The titanosaurs were diverse at the end of the Cretaceous of Brazil. Here we describe several new titanosaur remains of outcrops in the Cachoeira do Bom Jardim Formation, Cambambe Basin, (Upper Cretaceous), collected near the Jangada Roncador community, Chapada dos GuimarÃes municipality, Mato Grosso, Brazil. Although fragmentary, these specimens indicate the presence of two different sizes bone groups, suggesting, possible, at least two individuals. Despite not having enough diagnostic elements to identify a new species, they are different from the Brazilian species previously described. The area of study in this work has an importance, since with materials collected in this locality was described the species Pycnonemosaurus nevesi. Finally, the titanosaur's fauna of Jangada Roncador can be related to other occurrences, such as the Late Cretaceous Bauru Group, indicating a higher diversity of Brazilian titanosaurians than previously thought.
