Step 1: Define Carboniferous Period

The Carboniferous Period was a geologic period that lasted 358.9 to 298.9 million years ago.
It was distinguished by the abundance of plant life, particularly fern forests and early seed-bearing species.
These luxuriant forests eventually gave rise to vast coal reserves, now a major source of fossil fuels.
During the Carboniferous Period, different amphibians and early reptiles evolved, as did the development of Pangaea, a supercontinent that contained the majority of Earth's landmasses.
