    The Carboniferous, spanning 60 Ma, was an important period in Earth history, with major changes in atmospheric composition (in terms of both oxygen and carbon dioxide), the development of an icehouse world, the formation of vast tropical peat (coal) deposits, and the radiation of plants and animals on land.
