Crocodyloidea

Reptilia

Taxonomy
Crocodyloidea was named by Deraniyagala (1939) [almost certainly first used by Deraniyagala; could be attributed to Owen 1842 based on principle of coordination; also falsely attributed to Cuvier 1807 and Fitzinger 1826]. It is extant.

It was reranked as the unranked clade Crocodyloidea by Salisbury and Willis (1996), Salisbury et al. (2006), Brochu (2007), Brochu et al. (2009) and Rio and Mannion (2021).

It was assigned to Crocodylia by Salisbury and Willis (1996), Brochu (2007) and Brochu et al. (2009); to Eusuchia by Martin et al. (2010); to Brevirostres by Salisbury et al. (2006) and Farke et al. (2014); and to Longirostres by Rio and Mannion (2021).
