Upland areas of the continental interiors underwent substantial erosion during the Carboniferous.In order to simplify the huge amount of geological information, geologists have broken Earth's history down into sections which are called geological eras, periods, and epochs.Fossils records have shown that life existed for about 3,800 million years, but complex life emerged only about 600 million years. Their fossil record allows geologists to date and compare rocks across geological time.Join Britannica's Publishing Partner Program and our community of experts to gain a global audience for your work!Carboniferous Period, fifth interval of the Paleozoic Era, succeeding the Devonian Period and preceding the Permian Period.
