The present-day geological setting of the Mediterranean region is the result of the northward drift of the African-Arabian plates into Eurasia during the Cenozoic producing a vast variety of marine realms. During the Cenozoic Africa moved northwards into Eurasia with a mainly counterclockwise rotation involving several microplates. In between was the Neotethys ocean stretching from the Atlantic to the areas, where at present is the Indian Ocean. The Neotethys ocean continuously shrank until it was disintegrated into 3 parts: The Northern Paratethys (shrinked to the Black Sea), the Mediterranean Sea and the Indian Ocean. Nowadays the Mediterranean Region is characterized by manifold marine environments ranging from deap-sea, shelf, brackish till oxygen-depleted areas.

Remnants of these ancient realms and present ecosystems are found in the foraminiferal fossil record and present-day sediments. Samples randomly received or taken are used to illustrate the development of the Mediterranean region in the Cenozoic. Only basic conclusion of the foraminiferal record are presented here. Please refer to the mentioned references for deeper insights.
