Tethyan Trench
The Tethyan Trench was an ancient oceanic trench that existed in the northern part of the Tethys Ocean during the middle Mesozoic to early Cenozoic eras.
Geology
The Tethyan Trench formed when the northern moving Cimmerian Plate was subducting under eastern Laurasia, around 200 million years ago, in the Early Jurassic. The Tethyan Trench extended at its greatest during Late Cretaceous to Paleocene, from what is now Greece to the Western Pacific Ocean. Subduction at the Tethyan Trench probably caused the continents Africa and India to move towards Eurasia, which resulted in the opening of Indian Ocean. When the Arabian and Indian plates collided with Eurasia, the Tethys Ocean and the trench closed. Remnants of the Tethyan Trench can still be found today in Southeastern Europe and southwest of Southeast Asia.
other meaning of CENOZOIC ERA
Cenozoic Era, most recent of the major eras of geologic time, beginning about 65 million years ago and extending through the present. The Cenozoic follows the Cretaceous Period of the Mesozoic Era and is subdivided into the Paleogene and Neogene periods. Features of the Cenozoic are considered in articles under the names of the various shorter time periods (epochs) making up the era; in order, from earliest to latest, these are the Paleocene, Eocene, Oligocene, Miocene, Pliocene, Pleistocene, and Holocene.
