Using the draft genomes of " Chelonia mydas " and " Pelodiscus sinensis, " the team used the largest turtle data set to date in their analysis and concluded that turtles are likely a sister group of crocodilians and birds ( Archosauria ).

"' Pseudosuchia "'( " false crocodiles " ) is one of two major divisions of Archosauria and includes living crocodilians and all archosaurs more closely related to crocodilians than to birds ( what are often called " crocodilian-line archosaurs " ).

However, Harry Seeley disagreed with this interpretation, and split the Dinosauria into two orders, the Saurischia ( " lizard-hipped " ) and the Ornithischia ( " bird-hipped " ), which were seen as members of the Archosauria with no special relationship to each other.

It was placed as the sister taxon to a clade containing Archosauria and Erythrosuchidae, a derived than " Osmolskina ", " Sarmatosuchus ", " Fugusuchus " ( commonly thought to be an erythrosuchid ), and proterosuchids ( which were found to be paraphyletic ).

In his 2009 thesis on archosaur evolution, Sterling Nesbitt placed Spondylosoma at Archosauria " incertae sedis ", noting that the characters used by Galton to tentatively place the genus in Rauisuchidae are also found in Aetosauria, and that the holotype lacks characters to place it in either Pseudosuchia or Ornithodira.

In their review of putative euparkeriids from China, Richard Butler and colleagues concluded that " Wangisuchus " is a " nomen dubium " at Archosauriformes indeterminate because its holotype lacked diagnostic characters, even though the thecodont tooth implantation pointed to a closer relationship to Archosauria than to " Proterosuchus ".
47.
In a new 2009 study, " Vancleavea " was found to be more closely related to Archosauria than both " Erythrosuchus " and " Proterosuchus ", and was also found to be outside of the crown group, with " Euparkeria " remaining the closest sister taxon of Archosauria.

Genus " Redondasaurus " was first named by A . P . Hunt and S . G . Lucas in " A New Phytosaur ( Reptilia : Archosauria ) Genus from the Uppermost Triassic of the Western United States and Its Biochronological Significance, " published in the New Mexico Museum of Natural History & Science Bulletin in 1993.

Phylogenetic definitions of Pseudosuchia include " Crocodiles and all archosaurs closer to crocodiles than to birds " ( Gauthier and Padian ), " Extant crocodiles and all extinct archosaurs that are closer to crocodiles than they are to birds " ( Gauthier 1986 ), and more recently " the most inclusive clade within Archosauria that includes Crocodylia but not Aves " ( Senter 2005 ).
