The Tethys Ocean was a vast, ancient ocean that existed during the Mesozoic era, particularly prominent during the Cretaceous period. It separated the landmasses of Laurasia to the north and Gondwana to the south, influencing marine and terrestrial ecosystems, as well as the distribution of fossilized organisms. The ocean played a key role in the climatic and geological processes of the time, contributing to the development of diverse marine habitats.
