10 Prehistoric Islands Erased From the Map — And What We Found Beneath Them

Entire islands and continents once existed on the map — then quietly disappeared. Some sank under rising seas after the last Ice Age. Some vanished from official charts when they became inconvenient. Some were never erased at all… just never fully recognized. From the sunken Egyptian port of Thonis-Heracleion and the lost land of Doggerland, to Zealandia (the almost-completely submerged eighth continent), Beringia, Hy-Brasil, and the island that vanished from maps right when oil made it valuable. These are not myths. They are real places the ocean — and sometimes paperwork — decided to forget. What we found beneath them changes how the map of the past is drawn. Watch till the end.
