The crater Seleucus, 42 km in diameter, is shown in sunrise along the right (west) edge of the frame. The narrowness of its rim and the abrupt contact between its raised rim and the surrounding mare prove that the final mare flooding occurred after the crater was formed. In other words, the crater predates at least the youngest mare basalts in this area.
