How to Identify Fossils
Look for biological structure the rock around it lacks: shell curves and growth lines, the spongy honeycomb interior of bone, leaf veins, ribbed corals, or the segmented symmetry of a trilobite. Fossils usually contrast with their matrix in color or density. Bone that has mineralized feels heavier than fresh bone and often shows a polished brown-black surface.

Is it legal to collect fossils in Michigan?
Casual collecting is generally allowed on BLM and National Forest land for personal, non-commercial use — the standard BLM limit is 25 lbs per day plus one specimen. National parks, monuments, and many state parks prohibit collecting, and private land always requires the owner's permission. Check the site report for each location and verify current land status before you dig.

What should I bring to collect fossils?
The basics: a rock hammer, safety glasses, gloves, a bucket or padded bag for specimens, and a GPS app with the coordinates from this page. Add a spray bottle — wetting a stone makes color and banding far easier to judge in the field.
