A coral fossil with a whitish-gray look when dry. This is a very popular stone with collectors due to the "eyes" that appear when polished.
This is a coral stone with a bunch of chains interlocking. It is rare and not often found. The large stone is coral, but some others in the picture look like coral but are not. The coral white lines are always raised up higher than the tan part of the stone. It is from the Silurian in age and is from the U.P of Michigan.
Pink with green lines.
A horn shaped fossil - large on one side closing into a point.
