The Tethys Ocean, also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early Cenozoic Era, located between the ancient continents of Gondwana and Laurasia, before the opening of the Indian and Atlantic oceans during the Cretaceous Period.
The Tethys Ocean existed between the continents of Gondwana and Laurasia during much of the Mesozoic era. Several smaller versions have existed down to the present day. Today's Black Sea, Caspian Sea, and Aral Sea are remnants of the Tethys Ocean.
