A study of "Camposaurus arizoniensis" by Ezcurra and Brusatte discovered two unique features. This meant the specimen was a valid genus and species. "Camposaurus" is definitely a neotheropod. Based on phylogenetic analysis, its closest known relative is "Megapnosaurus rhodensis", because they share similarities in the tibia, and ankle. Spielman et al. (2007) put "Camposaurus" in the family Coelophysidae.
