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), Roberto-Da-Silva et al. (2018) 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), Roberto-Da-Silva et al. (2018) and Patrick et al. (2019).
