Answer 1

You could probably contact the Department of Geology at either USM or MSU and they can assist you.

Or, you could ask the Department of Geology in Jackson.

Answer 2

Thess links are pretty good. They may be able to direct you to the right people in your area, or identify the fossils from your photos. You have relics from the Kansas-Nebraska Sea, or Great Inland Sea! It forms everytime the Northern ice melts. It extended from where you are into Nebraska. Good luck! You are doing a wonderful thing! I'd love to hear how it comes out.
