It was assigned to Crocodilia by Gadow (1898) and Perrier (1928); to Loricata by Hay (1902) and Schmidt (1938); to Crocodylia by Walker (1970); to Crocodilia by Dollo (1883), Zittel (1890), Lortet (1892), Woodward (1898), Osborn (1904), Case (1904), Andrews (1906), Lambe (1908), Gilmore (1911), Roxo (1937), Kuhn (1946), Huene (1954), Estes (1964), Charig (1967), Miller (1967), Estes and Berberian (1970) and Bartels (1984); to Crocodylia by Willis (1993) and Williamson (1996); to Crocodylia by Kuhn (1966), Holman and Case (1988), Carroll (1988), Domning and Clark (1993) and Kraus (1998); to Crocodyliformes by Astibia et al. (2000) and Molnar et al. (2002); to Mesoeucrocodylia by Salisbury et al. (2006); to Crocodiliformes by Laurito and Valerio (2008); and to Neosuchia by Gasparini et al. (2006), Brochu et al.

Heterosuchus valdensis was named by Seeley (1887). Its type specimen is BMNH R36555, a set of vertebrae (procoelous cervical and trunk vertebrae), and it is a 3D body fossil. Its type locality is Heterosuchus valdensis type, which is in a Berriasian/Valanginian terrestrial horizon in the United Kingdom.

It was considered a nomen dubium by Salisbury and Naish (2011).
Crocodylus rollinati was named by Gray (1831). Its type specimen is MNHM AG 3 and 4 and is a 3D body fossil.

It was recombined as Pristichampsus rollinati by Berg (1966); it was considered a nomen dubium by Brochu (2013).
Crocodylus bolcensis was named by Sacco (1895). It is a 3D body fossil. Its type locality is Monte Purga, Vestenanova di Bolca, which is in an Eocene estuary/bay horizon in Italy.

It was considered a nomen dubium by Kotsakis et al. (2004).
Pristichampsus was named by Gervais (1853). It is not extant.

It was considered a nomen dubium by Brochu (2013).

It was assigned to Crocodylidae by Carroll (1988); to Alligatoroidea by Martin and Buffetaut (2008); to Crocodylia by Osi et al. (2007), Jouve et al. (2008) and Puértolas et al. (2011); and to Eusuchia by Martin et al. (2010) and Bronzati et al. (2012).
