Abstract

A theropod (Carcharodontosauridae) tooth exhibiting a split carina is the first recorded from upper Maastrichtian Marília Formation (Serra da Galga Member), Minas Gerais State, Brazil. The distal split carina has a distinct Y-shape. Split carinae have been reported elsewhere in Laurasian theropods (tyrannosaurids and allosaurids).
