the dinosaurs. We think we've shown that you can't rely on the dentition to determine what is an early dinosaur, which casts doubt on all the ornithischians from the Triassic of North America". Nearly complete specimens of R. callenderi were tested in a broad phylogenetic analysis of basal archosaurs for the first time when Sterling J. Nesbitt included the specimens PEFO 34561 and PEFO 34269 (a complete and a nearly complete skeleton, respectively) in his 2011 phylogenetic analysis. Revueltosaurus was placed at the base of the clade Suchia as the sister taxon to the armored and herbivorous aetosaurs. However, Revueltosaurus itself is not an aetosaur, since Aetosauria was redefined to exclude it. The analysis found Gracilisuchus, Turfanosuchus and the Revueltosaurus+Aetosauria clade to nest in a large polytomy with Ticinosuchus+Paracrocodylomorpha. The cladogram below follows Nesbitt (2011).
