When did Carboniferous begin and end?

The Carboniferous period began approximately 359 million years ago and ended around 299 million years ago. It is characterized by the extensive formation of coal deposits and the dominance of lush, swampy forests. This period is divided into two main epochs: the Mississippian and the Pennsylvanian. The Carboniferous is significant for its role in the evolution of both terrestrial ecosystems and atmospheric conditions.
