Michigan State of the United States of America

Michigan is a state in the Great Lakes and Midwestern regions of the United States. The state's name, Michigan, originates from the Ojibwe word mishigamaa, meaning "large water" or "large lake". With a population of about 10 million, Michigan is the tenth most populous of the 50 United States, with the 11th most extensive total area, and is the largest state by total area east of the Mississippi River. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies.

The Carboniferous is a geologic period and system that spans 60 million years from the end of the Devonian Period 358.9 million years ago (Mya), to the beginning of the Permian Period, 298.9 Mya. The name Carboniferous means "coal-bearing" and derives from the Latin words carbō ("coal") and ferō, and was coined by geologists William Conybeare and William Phillips in 1822.
