Fossils have been found in marine deposits from France, Germany and England. ''Pachycormus'' has recently been considered monotypic, only containing ''P.'' ''macropterus,'' with other species considered junior synonyms of the former, though this has subsequently been questioned. ''Pachycormus'' has generally been considered basal among Pachycormiformes, with a recent phylogeny finding it to be the second most basal pachycormiform after ''Euthynotus ''Euthynotus'' is an extinct genus of prehistoric bony fish that lived during the early Toarcian stage of the Early Jurassic e ...
