“The early evolution of theropod dinosaurs is poorly understood,” said Dr. Rodrigo Müller, a paleontologist in the Centro de Apoio a Pesquisa Paleontologica da Quarta Colonia at the Universidade Federal de Santa Maria.
“Whereas sauropodomorphs are well-known from the oldest dinosaur bearing outcrops, the record of theropods is fragmentary and ambiguous.”
“The Triassic deposits from Brazil yielded some of the oldest dinosaurs worldwide.”
