The term "Carboniferous" comes from England, in reference to the rich deposits of coal that occur there. These deposits of coal occur throughout northern Europe, Asia, and midwestern and eastern North America. The Pennsylvanian* saw the disappearance of the warm, shallow seas of the Mississippian, causing a dramatic change in marine life. The warm, clear seas of the Mississippian gave way to cool, muddy waters resulting in a decline in crinoids from which they never recovered. ... The engravings are from Dana, James D.

They have created a tool for measuring geologic time, breaking it into useable, understandable segments. For the purposes of geology, the “calendar” is the geologic time scale.

The term "Carboniferous" is used throughout the world to describe this period, although this period has been separated into the Mississippian (Lower Carboniferous) and the Pennsylvanian (Upper Carboniferous) in the United States. This system was adopted to distinguish the coal-bearing layers of the Pennsylvanian from the mostly limestone …. Jonathan cannon football
