The Carboniferous is a geologic period

The Carboniferous is a geologic period and system that extends from the end of the Devonian Period, about 359.2 ± 2.5 Mya (million years ago), to the beginning of the Permian Period, about 299.0 ± 0.8 Mya (ICS, 2004,[5] chart).

The Carboniferous was a time of glaciation, low sea level and mountain building, diversification and extinction; a minor marine and terrestrial extinction event among animals and plants (Carboniferous rainforest collapse)occurred in the middle of the period caused by climate change.[6]

The name comes from the Latin word for coal, carbo. Carboniferous means "coal-bearing". Many coal beds were laid down globally during this period, hence the name.
