Carboniferous Period

The Carboniferous period is a geologic period that lasted from about 359 to 299 million years ago. It is known for the vast deposits of coal that formed during this time, hence the name "Carboniferous" which means "coal-bearing" in Latin.

Environment

The Carboniferous was a time of significant geological, climatic, and evolutionary changes. It was characterized by extensive swampy forests and high levels of atmospheric oxygen. These conditions were ideal for the growth of large, tree-sized plants such as ferns, horsetails, and early seed-bearing plants.

Climate

The climate during the Carboniferous was generally warm and humid, with the equator experiencing tropical conditions and the poles being covered in ice caps. The high levels of atmospheric oxygen also facilitated the growth of giant insects, some with wingspans of over 2 feet.

Life Forms

The Carboniferous period saw the evolution of early reptiles and the diversification of amphibians. The large forests provided habitats for a variety of terrestrial and aquatic organisms, including early insects, spiders, and fish.
