It was once considered a key player in the geological history of our planet. However, scientists are now thinking it may never have existed. Only in the minds of some earth scientists. The doubt arises as a result of the application of modern dating techniques for rock formations.
Another more interesting and more recent piece of geology is worth looking at. See https://phys.org/news/2026-01-ancient-tethys-ocean-central-asia.html … this sounds like the the mid ocean seaway running straight through the North American continent during the Cretaceous. Here we have the existence of an ancient ocean in central Asia. This also involves mountain building and how it might have come about. The Mediterranean Sea, we are told, is thought to be a remnant of the much move extent Tethys Ocean. Needless to say the Cretaceous is also involved. Modeling was also involved. Not necessarily negatively but enough to raise a question mark in a catastrophist mind. The research looks at the creation of the landscape in central Asia that may have led to the longevity of a big pool of water. Conveniently situated on the boundary of several plates, as well as the heart of the Asian landmass. The Tethys ocean is dragged in so as to explain the nature of the landscape. Even though they also acknowledge that over the last 250 million years central Asia was mainly on the dry side.
The mid continent sea way in North America lies directly on the path of a wall of water created by the Chicxulub crater. Dinosaur remains abound along the course of the seaway. Many of them broken and tossed by water. Did something similar happen across ancient Euroasia? Shallow seas are thought to have existed across most of western Europe, a watery world that reached as far as Kazakhstan. Was the Tethys Ocean real? Or was it just the course of a huge surge of ocean water that occurred over a short period of time as a result of pole shift or the asteroid strike. The residue of the water may have remained in some locations – and that might include Kazakhstan. Once these ideas are implanted in your head you can read the link with different thoughts running through your brain. We don’t know – either way. Fascinating subject if sedimentary layers were laid down, often, very quickly.
