- Young, 1964 was formerly regarded as a species of " Proterosuchus ", but it was recently re-assessed as not belonging to a proterosuchid and instead a " nomen dubium " referable to Archosauria.
- These analyses revealed little change in the relationships ( apart from the constraints themselves ), but major chances to the traits associated with these relationships, changing the traits that were considered to diagnosed Pseudosuchia, Archosauria, and other clades.
- Gauthier's corpus is remarkable in that he contributed the foundational phylogenetic studies of Archosauria and Lepidosauria, two major amniote clades; and he was the primary author of the foundational and still widely cited phylogenetic study of Amniota as a whole.
- According to Nesbitt ( 2009 ), this trait is absent in Archosauria with the possible exception of " Arizonasaurus " and " Poposaurus ", but was used as a synapomorphy of Erythrosuchia in Parrish ( 1992 ) phylogenetic analysis.
- This group also includes all extinct non-avian dinosaurs, extinct crocodilian relatives, and pterosaurs . "'Archosauria "', the archosaur clade, is a crown group that includes the most recent common ancestor of living birds and crocodilians.

- Within diapsids, some place turtles within Archosauria, or, more commonly, as a sister group to extant archosaurs, though an analysis conducted by Lyson " et al . " ( 2012 ) recovered turtles as the sister group of lepidosaurs instead.
- Therefore, it's not clear if " Nundasuchus " is either a suchian that has convergences with far more basal archosaurs as the two phylogenetic analyses suggest, or an archosauriform related to Archosauria, with convergent morphology to the more advanced paracrocodylomorphs.
