Resumen:
An isolated caudal vertebral centrum of a theropod dinosaur was discovered in the Bauru
Basin (Late Cretaceous) of Brazil, in the Maastrichtian São José do Rio Preto Formation. The
vertebral centrum has pneumatic features that are similar to those in the megaraptoran
theropods Aerosteon, Megaraptor, and Orkoraptor. For example, all these taxa share with
the caudal centrum here described the presence of true pleurocoels or pneumatic foramina,
immersed within a depression or fossa. Thus, the specimen is considered the first record
of Megaraptora in Brazil. The present analysis provides new information on the vertebral
caudal anatomy of this clade of bizarre Cretaceous theropods.
