We report new theropod dinosaur material from the Presidente Prudente
Formation (Campanian–Maastrichtian), Bauru Group, in southwestern São
Paulo state. The material comprises a fragment of right maxilla of
Carcharodontosauridae, an anterior portion of a left ilium of
Abelisauroidea and a proximal portion of a right fibula of a
coelurosaurian. Previous theropod records from the Bauru Basin
comprise Abelisauridae and Tetanurae and in São Paulo state these have
been represented by only a right premaxilla of an abelisaurid and
isolated abelisaurid and carcharodontosaurid teeth. The new material
reported here represents the first theropod remains from the
Presidente Prudente Formation, and includes the first abelisauroid and
coelurosaurian postcranial remains from the Bauru Basin in São Paulo
state and the first latest Cretaceous carcharodontosaurid known from
non-dental remains anywhere.
