Trigonosaurus (meaning "triangle lizard" after Triangulo Mineiro, where it was found^[1]), is a genus of saltasaurid dinosaurs from the Maastrichtian Marília Formation of Brazil. The type species, Trigonosaurus pricei, was first described by Campos, Kellner, Bertini, and Santucci in 2005. It is based on two specimens, both consisting mainly of vertebrae. Before its description, it was known as the "Peirópolis titanosaur", after the place it was found.^[1]
