Carboniferous Period

The Carboniferous period, which lasted from about 359 to 299 million years ago, is an important time in Earth's history. It is known for the widespread development of forests and the eventual formation of coal deposits, hence the name "Carboniferous," which means "coal-bearing."

Key Points to Remember

1. The Carboniferous period is divided into two parts: the Mississippian and the Pennsylvanian.
2. During the Carboniferous period, Earth's landmasses were joined together in the supercontinent Pangaea.
3. The climate during this time was warm and humid, leading to the growth of vast swampy forests.
4. These forests were dominated by giant ferns, club mosses, and horsetails, which eventually formed the coal deposits we use today.
5. The high oxygen levels during the Carboniferous period allowed for the evolution of large insects, such as dragonflies with wingspans of up to 30 inches.
6. Early amphibians and reptiles also began to diversify and inhabit the land during this time.
