In the early Carboniferous, their rich remains (particularly stem fragments) were solidified into rock called crinoidal limestone. Indiana limestone, like all limestone, is a rock primarily formed of calcium carbonate. It was deposited over millions of years as marine fossils decomposed at the bottom of a shallow inland sea which covered most of the present-day Midwestern United States during the Mississippian Period.Mammal Fossils-Antelope,Mammoths. 13 km SE on Arroyo del Valle SE1/4t4sr2e.
