Reptilia -

Phytosauria was named by Jaeger (1828). It is not extant. It was considered monophyletic by Stocker (2010) and Nesbitt (2011).

It was reranked as the order Phytosauria by Osborn (1903) and Osborn (1903); it was synonymized subjectively with Parasuchia by Kuhn (1946), Kuhn (1964) and Kuhn (1966); it was reranked as the unranked clade Phytosauria by Hungerbühler (2002), Stocker (2010), Nesbitt (2011) and Ezcurra (2016).

It was assigned to Diapsida by Osborn (1903) and Osborn (1903); to Parasuchia by Osborn (1904), Lull (1915), Lull (1917) and Roxo (1937); to Thecodontia by Baird (1957) and Carroll (1988); to Suchia by Weinbaum and Hungerbühler (2007); to Archosauria by Stocker (2010); to Crurotarsi by Hungerbühler (2002) and Nesbitt (2011); and to Pseudosuchia by Ezcurra (2016).

If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

M. R. Stocker 2010A stem-based group that is the most inclusive clade containing Rutiodon carolinensis (Emmons 1856) but not Aetosaurus ferratus (Fraas 1877), Rauisuchus tiradentes (Huene 1942), Prestosuchus chiniquensis (Huene 1942), Ornithosuchus woodwardi (Newton 1894) or Crocodylus niloticus (Laurenti 1768).
