**Definition-** The name CARBONIFEROUS comes from the latin word of coal (//carbo)//. The word carboniferous means "coal-bearing."
The Carboniferous is a time period from about 354 to 290 million years ago. Carboniferous period caused a large increase in forestation which caused a decrease in carbon dioxide in the atmosphere and an increase of oxygen. Oxygen levels peaked at a 35%. Due to this large increase of oxygen it is believed that insects could easily become as large as they were during the carboniferous period. The early carboniferous period was cooler, in the later years it was warm. The environment was the perfect place for the creation of coal to begin. One of the key evolutionary feats in this time period was the evolution of amniotic eggs which allowed animals to lay eggs on land; leading to the mammals, reptiles, and birds. The amphibians evolved during this period of time into the first land reptiles Late Carboniferous was caused by the collision of Laurussia into Godwanaland this later lead to the formation of the Appalachian Mountains. IT CREATED THE SUPERCONTINENT AKA PANGEA!! The carboniferous era is divided into two different time periods known as the Mississippian (Lower Carboniferous) and the Pennsylvanian (Upper Carboniferous). This system was adopted to distinguish the coal-bearing layers of the Pennsylvanian from the limestone Mississippian. LIFE IN THE CARBONIFEROUS WAS COMPOSED OF ALL INSECTS AND REPTILES AND FISH The trilobites started to become extinct during this time period.
