Today Germany's largest wine-growing region, once a fascinating water world. The history of the "Mainz Basin" began about 45 million years ago: The Upper Rhine Graben subsided and the region was flooded several times. Both by the sea from the North Sea basin and by water from the then Mediterranean area. What remained were fossils and sediments, such as snails, shark teeth or manatee skeletons.
