The Paleo-Tethys Ocean was an ancient Paleozoic ocean. It sat where the Indian Ocean and Southern Asia are now located. It was located between the paleocontinent Gondwana and the so called Hunic terranes. These are divided into the European Hunic (today the crust under parts of Central Europe (called "Armorica") and Iberia) and Asiatic Hunic (today the crust of China and parts of eastern Central Asia). A large transform fault is supposed to have separated the two terranes.
