Abstract. Sea levels have been determined for most of the Paleozoic Era (542 to 251 million years ago), but an integrated history of sea levels has remained unrealized. We reconstructed a history of sea-level fluctuations for the entire Paleozoic by using stratigraphic sections from pericratonic and cratonic basins. Evaluation of the timing and ...The Paleozoic Era is known as "Ancient Life". The Paleozoic Era is divided into six different periods. During this time, many major events that occurred led to the development of new organisms. Changes in the environment, climate, and the surface of the Earth led to the evolution of new organisms. A lot of new complex organism evolved ...
