Taxonomy

The name ''Mycterosuchus'' was coined for ''Steneosaurus nasutus'' by Andrews in 1913 in his catalogue of thalattosuchians from the Oxford Clay of southern England. The genus name is derived from the Latin word for nose (''mycto'') and the Greek word for crocodile (), together meaning . ''Mycterosuchus nasutus'' was synonymized with ''Steneosaurus leedsi'' by Adams-Tresmand in 1987, but is recovered as a distinct species in the cladistic analysis of Osi ''et al''. of 2018.S. M.
