Resumen:
ABSTRACT: An almost complete skull of a carnosaur from the Allen Formation (Maastrichtian of Río Negro Province) is described as the holotype of Abelisaurus comahuensis. It is a high skull with a broad interorbital roof, a huge antorbital fenestra, squamosal nearly horizontal with the quadratojugal process ventrally directed, very wide lower temporal fenestra, very long quadrate, large orbital fenestra with almost closed orbits. The differences with Tyrannosauridae and other Cretaceous carnosaur families appear so significant as to propose a new family, Abelisauridae, probably of Gondwanan distribution.
