Superb Olenellus clarki California Trilobite with Axial Spines

Olenellus are quite rarely found with more than a cephalon, Ruin Wash in Nevada is a notable exception. This specimen is from a very old collection, and is from a locality that is no longer collectable. Here is a superb example of a Olenellus clarki with the axial spines which are very rarely present.
