Strat unit: Thunder Bay formation

Submitter notes: This view shows the crinoid stem and the thickness of the corals which are comparatively thin. The coral is 3/4' or 20 mm by 3/4' or 20 mm by 1/4' or 7 mm thick. I am sure many of my friends in FUMMP have better examples of this unusual coral they could show.
