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.

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.
