WebbL' océan Iapétus, encore appelé océan proto-Atlantique, est un ancien océan (ou paléo-océan) ayant existé au Paléozoïque, de la fin du Précambrien au Silurien lorsqu'il s'est refermé il y a 420 millions d'années. Il séparait le paléocontinent Laurentia des paléocontinents Baltica et Avalonia dans l' hémisphère Sud . Iapetus is a moon of Saturn. It is the 24th of Saturn’s 83 known moons.
