Is the Mediterranean a remnant of tethys sea?

Yes, the Mediterranean Sea is a remnant of the ancient Tethys Sea. The Tethys Sea was a vast oceanic body that existed between the continents of Laurasia and Gondwana during the Mesozoic Era. It stretched from the present-day Atlantic Ocean to the Indian Ocean and covered much of what is now the Mediterranean Sea, as well as parts of North Africa, Europe, and Asia. Over time, the Tethys Sea gradually closed due to the collision of the African and Eurasian tectonic plates, resulting in the formation of the Mediterranean Sea and other smaller bodies of water.
