This is a fantastic example of a cluster of trilobites and fossil. Although common, the Tristani is rarely in the condition that these two specimens are in. Here, the rock opens into a lid and a base - three parts. On the top, the smaller compartment shows a pristine Tristani specimen with exquisite detail. The larger compartment opens to show a smaller perfect specimen and a gastropod also. Opening this really brings out the "wow" factor.
