The phanerozoic aeon is defined as the geological period which extended from about 590 million years ago to about 245 million years ago. The actual period began about 544 million years ago and ended about 249 million years ago.

      The Paleozoic Era was there about 543 to 248 million years before. The word means Ancient Life. This era was basically the one of the three earliest geological eras. At that time, there were six major continents that formed the land masses. Africa was at the South Pole and North America ran west an east of the equator. There were incursions of the seas and there were large projections of limestone.  There was also coal which were in the Western Europe. These deposits of coal and limestone were formed during the Paleozoic era.
