Panthalassa (Wikipedia)
Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν “all” and θάλασσα “sea”), was the superocean that surrounded the supercontinent Pangaea, the latest in a series of supercontinents in the history of Earth. During the Paleozoic–Mesozoic transition c. 250 Ma it occupied almost 70% of Earth’s surface. Its ocean floor has completely disappeared because of the continuous subduction along the continental margins on its circumference. Panthalassa is also referred to as the Paleo-Pacific (“old Pacific”) or Proto-Pacific because the Pacific Ocean is a direct continuation of Panthalassa.- Babylon (Wikipedia)
Babylon is an ancient city located on the lower Euphrates river in southern Mesopotamia. Babylon functioned as the main cultural and political centre of the Akkadian-speaking region of Babylonia, with its rulers establishing two important empires in antiquity, namely the 18th century BC Old Babylonian Empire and the 7th–6th century BC Neo-Babylonian Empire, and the city would also be used as a regional capital of other empires, such as the Achaemenid Empire. Babylon was one of the most important urban centres of the ancient Near East until its decline during the Hellenistic period.
