Pseudosuchia

Reptilia

Taxonomy
Pseudosuchia was named by Zittel (1890). It was considered monophyletic by Nesbitt (2011).

It was reranked as the order Pseudosuchia by Gadow (1898) and Perrier (1928); it was synonymized subjectively with Aetosauriformes by Hay (1930); it was corrected as Pseudosuchida by Kuhn (1971); it was reranked as the unranked clade Pseudosuchia by Gauthier and Padian (1985), Gauthier et al. (1989), Parker (2007), Schoch (2007), Nesbitt (2011), Lautenschlager and Desojo (2011), Ezcurra (2016) and Patrick et al. (2019).

It was assigned to Crocodilia by Gadow (1898) and Perrier (1928); to Parasuchia by Roxo (1937); to Thecodontia by Huene (1922), Kuhn (1946), Bock (1952), Huene (1954), Haughton and Brink (1954), Huene (1958), Kuhn (1964), Kuhn (1966), Charig (1967), Kuhn (1971), Haubold (1971) and Haubold (1974); to Crocodilomorphi by Cooper (1981); to Archosauria by Gauthier and Padian (1985); and to Archosauria by Gauthier et al. (1989), Parker (2007), Schoch (2007), Nesbitt (2011), Lautenschlager and Desojo (2011), Ezcurra (2016) and Patrick et al. (2019).
