Six million years ago, a vast ocean--which scientists have named Tethys--vanished from the face of the earth. Vanished Ocean tells the fascinating story of Tethys, offering an illuminating account of the scientific evidence for the ocean's existence. World-renowned geologist and oceanographer Dorrik Stow describes the powerful forces that shaped the ocean; the marine life it once held and the rich deposits of oil that life left behind; and the impact of its currents on environment and climate. The story of Tethys is also a story of extraordinary episodes such as the virtual drying up of the Mediterranean, before being filled again by a dramatic cascade of water over the straits of Gibraltar. Along the way, Stow reveals how geologists and oceanographers spent years proving the former existence of Tethys, from a remarkable series of clues locked away in rocks now exposed high up in mountain ranges and buried in sediments deep beneath today's oceans. Indeed, these myriad clues are now sca
