| 1. | The Archosauria includes crocodylians, birds, and their extinct relatives.
|
| 2. | Evidence currently, however, only likely points to basal Ornithodira or Archosauria.
|
| 3. | However, its classification within Archosauria is uncertain, as the known remains are fragmentary.
|
| 4. | It could take many positions within Archosauria, but none were as a sister taxon of Crocodylomorpha.
|
| 5. | As in Gauthier's tree, Benton and Clark's revealed a basal split within Archosauria.
|
| 6. | Proterochampsia was found to be the sister taxon of Archosauria, whose living representatives consist of birds and crocodilians.
|
| 7. | Instead, erpetosuchids formed a polytomy or unresolved evolutionary relationship at the base of Archosauria along with several other groups.
|
| 8. | Being more derived than these other taxa, " Koilamasuchus " is closer to the crown group Archosauria.
|
| 9. | According to the current consensus, Aves and Crocodilia are the sole living members of an unranked clade, the Archosauria.
|
| 10. | In Sterling Nesbitt's 2011 monograph on early archosaurs, a phylogenetic analysis found strong support for phytosaurs falling outside Archosauria.
