Need help identifying - found on Lake Michigan

Found this, and a ton more, with my daughter over the years.

 

Found this on Lake Michigan, near South Haven - Coldwater Shale Formation/Mississippian/Devonian

 

There are lots of braciopods, from what I can see. Some having an amber looking coating, others having a metallic coating.

 

Can anyone help with this, before I start to polish it (and let me know if I shouldn't). I've always just picked up rocks and coral fossils at the beach, and just now have really started to get curious....so I'm new to this, forgive me if I've missed anything. 

 

There are some close up shots, with a tootsie roll for scale...only thing I could find lol.

Looks like brachiopod shells all glommed up together. Polishing might be fine, I think.
