 The genera "Boverisuchus" and "Weigeltisuchus" from the Lutetian of Germany as well as "Limnosaurus" from North America were synonymized with "Pristichampsus" and their type species were reassigned to it.Langston (1975) found "Limnosaurus" to be based on non-diagnostic remains, and therefore considered it to be in its own genus, as a "nomen dubium".He also reassigned "Crocodylus vorax" from the Lutetian of Wyoming and West Texas to "Pristichampsus".
