Joseph Fossil Posted October 12, 2022 Share Posted October 12, 2022 I've been looking recently into possibly fossil hunting by Alton, Illinois for specimens of Mississippian era fauna. I'm specifically looking for general places like roadcuts and quarries with 330-340 million year old St. Louis Limestone (Meramec group) in the Alton area. I'm just wondering (without anyone being too specific about localities) is there any general places like quarries or roadcuts that match that description in Alton, Illinois?
