abstract:The Pannonian Sea was a shallow ancient sea located in the area today known as the Pannonian Plain in Central Europe. The Pannonian Sea existed during the Miocene and Pliocene epochs, when three to four kilometres of marine sediments were deposited in the Pannonian Basin.
Beyond the capital, rugged Alpine mountains rise to the north and west, the Pannonian plains stretch off towards Hungary in the east and the the Adriatic Sea lies to the south.
