Isolated bones of abelisauroid theropods from the Bauru Group (Late
Cretaceous, Brazil), are described. They correspond to three
individuals represented by fused ischia and part of the ilium, a
partial axis, and a right fibula, respectively. The fossils come from
different sites in the municipalities of Ibirá (axis and fi bula) and
Monte Alto (ilium and ischia), São Paulo State, from Maastrichtian
beds of the São José do Rio Preto and the Marília formations (Bauru
Group), respectively. The specimens provide new information on
abelisauroids which are still poorly known in the Brazilian fossil
record, and on the distribution of this diverse group of theropod
dinosaurs in South America. These discoveries indicate that
abelisauroids were the most common large predatory dinosaurs in the
outcrops where they come from.
