The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, and the North American Inland Sea) was a large inland sea that existed during the Mid-to-Late Cretaceous period, splitting the continent of North America into two landmasses, Laramidia to the west and Appalachia to the east. The ancient sea stretched from the Gulf of Mexico and through the middle of the modern-day countries of the United States and Canada, meeting with the Arctic Ocean to the north. At its largest, it was deep, wide and over long.
