Crocodylia (crocodilian)

Reptilia

Taxonomy
Crocodilia was named by Owen (1842) [originally spelled Crocodilia by Owen; corrected by Wermuth 1953; also falsely attributed to Laurenti 1768 (based on naming of Crocodylus) and Gmelin 1789 (see Dundee 1989)]. It is extant. It was considered monophyletic by Thies et al. (1997).

It was synonymized subjectively with Emydosaurii by Bonaparte (1850); it was reranked as the subclass Crocodilia by Gadow (1898) and Perrier (1928); it was synonymized subjectively with Loricata by Hay (1902) and Hay (1930); it was reranked as the suborder Crocodili by Jaekel (1910) and Jaekel (1911); it was corrected as Crocodylia by Kuhn (1966), Haubold (1971), Bakker and Galton (1974), Haubold (1974), Cooper (1981), Holman and Case (1988), Carroll (1988), Frank and Ramus (1996), Thies et al. (1997), Sereno et al. (2001), Peng et al. (2001) and Pearson et al. (2002); it was reranked as the suborder Crocodylia by Walker (1970); it was reranked as the unranked clade Crocodilia by Gardiner (1982); it was reranked as the unranked clade Crocodylia by Gauthier et al. (1989), Williamson (1996), Brochu (2000), Molnar et al. (2002), Brochu (2004), Hua and Jouve (2004), Brochu (2006), Salisbury et al. (2006), Turner (2006), Brochu et al. (2009), Andrade et al. (2011), Bronzati et al. (2012), Rio and Mannion (2021) and Burke et al. (2024).

It was assigned to Sauria by Owen (1859); to Sauropsida by Baur (1887); to Diapsida by Osborn (1903) and Osborn (1903); to Diaptosauria by Osborn (1904); to Loricati by Jaekel (1910) and Jaekel (1911); to Archosauromorpha by Huene (1954); to Archosauria by Kuhn (1966); to Crocodylomorpha by Walker (1970); to Archosauria by Gardiner (1982); to Crocodyliformes by Gauthier et al.
