Did the Sahara desert used to be an ocean?

What is the water in the Sahara Desert?
Water in the Sahara Desert. This sandstone, which occurs beneath most of the Sahara Desert, is about 900 meters (3000 feet) thick and stores enormous quantities of groundwater, estimated to be in excess of 18,000 cubic kilometers (4300 cubic miles). The antiquity of this water has been confirmed by radiocarbon dating (see Chapter 8).
What are facts about the Sahara Desert?
