Extinct genus of reptiles

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]
