It is best known as an era where there were vast swamps and forests, hence the name “carboniferous” which means producing or containing carbon or coal. On the other hand, the Devonian period happened about 416-359 million years agoThe Carboniferous Period consists of two subperiods: the Pennsylvanian and the Mississippian. Pennsylvanian subperiod (323 million years ago to 299 million years ago): Cycles of shallow seas, swamps, and river channels resulted in deposits of limestone, sandstone, and shale that are found at the surface in eastern Kansas. Devonian extinctions, a series of mass extinction events primarily affecting the marine communities of the Devonian Period (419.2 million to 359 million years ago). At present it is not possible to connect this series definitively with any single cause. It is probable that they may record a combination of several stresses—such as excessive sedimentation, rapid …Devonian. In the Devonian Period, Britain lay south of the equator and had a semi-arid climate. Marine limestones, sandstone and mudstones were developed in the south-west.
