Hi From Michigan!
I had a great time finding fossils along the Northeast shoreline of Lake Michigan (in the Leelanau Bay, just outside of Charlevoix) this summer. Along with my usual haul of horn corals and crinoids (and two intact bivalves!!), I found these two pieces interesting. Fossil A is a real soup, and I'd like help identifying pretty much anything you see in the picture, especially the thing that looks like an insect. I'm not sure if Fossil B is actually a fossil or a geological formation; otherwise, my best guess is a type of coral?
Thanks in advance!
