Panthalassa
From Free net encyclopedia
Current revision
Panthalassa (Greek for "all seas") was the vast global ocean that surrounded the supercontinent Pangaea during the late Paleozoic era and the early Mesozoic era. It included the vast Pacific Ocean on the west and north and the Tethys Ocean to the southeast. It became the Indian and Pacific Oceans following the closing of the Tethys basin and the breakup of Pangaea which created the Atlantic and Arctic Ocean basins.
In the map on the right, the earth's equator was a line that roughly crossed the spot where Spain, Morocco (Casa Blanca), and Boston met. South of that line, the land mass was called Gondwana. North of the line, it was named Laurasia.
Gondwana, sometimes called Gondaranya, is a region of central India, and is named after the Gondi people who live there and in various other parts of India. The ancient continent of Gondwana was so named because some of the earliest rock formations of this continent were first investigated in part of that Indian region, now known as Orissa.
Pan is Greek for "all", and gaea comes from the Greek γη or Γαια, meaning "earth"—hence Pangaea (all earth).
