''Boverisuchus'' is an extinct genus of planocraniid crocodylian known from the middle Eocene (Lutetian stage) of Germany and western North America. It grew to approximately three metres (10 ft) in length. The type species ''Boverisuchus magnifrons'' was first named by paleontologist Oskar Kuhn in 1938, from the Lutetian of Germany alongside ''Weigeltisuchus geiseltalensis''. Most paleontologists have considered both species to represent junior synonyms of the type species of ''Pristichampsus'', ''P. rollinatii''. Following a revision of the genus ''Pristichampsus'' by Brochu (2013), ''P. rollinati'' was found to be based on insufficiently diagnostic material and therefore is a ''nomen dubium'' while ''Boverisuchus'' was reinstated as a valid genus. Brochu (2013) also assigned ''Crocodylus vorax'', which has been referred to as ''Pristichampsus vorax'' since Langston (1975), as the second species of ''Boverisuchus''. According to Brochu (2013), material from the middle Eocene of Italy and Texas may represent another yet unnamed species. The two Asian species of ''Planocrania'' were found to be most closely related to ''Boverisuchus'' using a phylogenetic analysis. The name Planocraniidae was reinstated to contain these genera and replace Pristichampsidae.〔 ==References==
