Résumé

Titanosaurs were the most diverse herbivorous dinosaurs during the Late Cretaceous of Brazil. Although new titanosaur fossils have been found in recent decades, most of these records are from a few areas in the southeast region of Brazil, while other sites from the midwest of the country have been little explored and few specimens from this region have been described, which has created significant knowledge gaps. The present study describes new Upper Cretaceous materials from the state of Goiás. Despite their fragmentary nature, the specimens have anatomical information that supports their taxonomic identification as Titanosauria. These new records represent an important addition to the Late Cretaceous faunal diversity of this region, which will stimulate new research that may increase knowledge on Brazilian dinosaurs, and more generally on some of the last dinosaur faunas of South America before the end-Cretaceous asteroid impact and extinction.
