[7] Fossil lungfish burrows are another interesting find from the Pennsylvanian coal swamp deposits near Grand Ledge in Clinton County but these tend to be poorly preserved. This warm climate, along with the existence of a shallow inland ocean (in the geographic region now occupied by the Great Lakes) led to a marine life much like that seen in the coral reefs of the Caribbean.
