Camposaurus
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.
