Trajectory and contribution of geoscientists (1906–1961) to dinosaur research in the Bauru Group (Cretaceous) in the Triângulo Mineiro region of Brazil

•The development of paleontological research in the Triangulo Mineiro region.•The description of the trajectory of paleontologists who contributed to the studies of the region.•The work of paleontologists in the Triângulo Mineiro region, during twentieth century.

The present study discusses geological and paleontological research conducted by geoscientists in the Late Cretaceous Bauru Group, of the Triângulo Mineiro region, Brazil. This analysis based largely on historical documentary sources focuses on the pioneering work of geoscientists, who made numerous discoveries of dinosaur fossils. This work contributes to a chronological survey that has been compiled on the geological studies in the Bauru Group, and describes the importance of the paleontological discoveries made during the twentieth century.
