Species

Eoneustes (meaning "dawn swimmer") is an extinct genus of metriorhynchoid crocodyliform from Middle Jurassic (late Bajocian to early Bathonian stage) deposits of France. Eoneustes was a carnivore that lived in the oceans and spent much, if not all, its life out at sea.[1]

Discovery and species

  • E. bathonicus:[2] Western Europe (France) of the Middle Jurassic (early Bathonian). It is known from holotype from Calvados of Normandy, that lost during the Second World War.[3]
  • E. gaudryi:[4] Western Europe (France) of the Middle Jurassic (late Bajocian to early Bathonian). It is known from the holotype NHM R.3353, a partial skull from Côte d’Or, Burgundy and the referred specimen from which housed at Université Claude Bernard Lyon I, F.S.L. 330210, another partial skull from Alpes-de-Haute-Provence, France.[3]
