       Camposaurus is very similar in appearance to the far more famous Coelophysis,‭ ‬so much so in fact that for just over ten years after the genus was named there was a lot of speclation that the genus was probably synonymous with Coelophysis.‭ ‬This speculation ended in‭ ‬2011‭ ‬however after a study by Martin Ezcurra and Stephen Brusatte clearly identified autapomorphies in the leg which are not seen in Coelophysis.‭ ‬The conclusion is that while Camposaurus is superficially similar to Coelophysis,‭ ‬it is still different enough to be a distinct genus.‭ ‬Camposaurus is also regarded as one of if not‭ ‘‬the‭’ ‬oldest neotheropod dinosaurs,‭ ‬the sub group of the Theropoda that would go on to develop all of the more advanced theropod dinosaurs.‭
       Camposaurus would have been a small‭ ‬lightweight predator that‭ ‬probably focused upon hunting smaller animals such as lizards as well as possible juveniles of other dinosaurs.‭ ‬Due to the small size however,‭ ‬Camposaurus would‭ ‬have had to stay out of the way of potentially other larger dinosaurian predators,‭ ‬and most certainly out of the way of large rauisuchians such as Postosuchus that were hunting in the same locations and at the same approximate time as Camposaurus.
