“A peculiarity of this dinosaur is that it has cavities in the ear area that other abelisaurids did not have, which could have given this species different auditory capacities, possibly a greater hearing range,” Federico Gianechin, one of the lead authors of the study told CNN. “This, together with its keen sense of smell, would have given great capabilities as a predator to this species.”

The remains were found in the Bajo de la Carpa Formation, which is a body of rock in Argentina’s Rio Negro and Neuquén provinces.
