Here is a fabulous multiple slab of trilobites from the Ordovician of Morocco. There are two Ampyx priscus and one Calymenella trilobites on this plate - quite unusual to have both types present on the same plate. The trilobites have excellent orangish color and contrast wonderfully with the greyish-brown matrix. The detail on all three trilobites is just exquisite. This is an excellent association plate of two very different types of Ordovician trilobites.
