Etymology De Quilmes (une cité ancienne en Argentine) et du Grec ''sauros'', lézard.

Quilmesaurus is a genus of carnivorous theropod dinosaur from the Upper Cretaceous Allen Formation of Argentina. It was a member of Abelisauridae, closely related to genera such as Carnotaurus. The only known remains of this genus are leg bones which share certain similarities to a variety of abelisaurids. However, these bones lack unique features, which may render Quilmesaurus a nomen vanum.
