11.2" Ordovician Trilobite (Dikelokephalina) - Excellent Preservation

This is a large, 11.2" long, Lower Ordovician trilobite (Dikelokephalina brenchleyi) from Ouled Slimane, Morocco. The preservation on this example is very nice, and the orange shell contrasts well with the light colored shale. Only some minimal restoration along repaired cracks through the left hand side of the tail and thorax. I've rarely seen examples of this trilobite this nice.

Trilobites of the genus Dikelokephalina from Ordovician Gondwana and Avalonia

Trilobites were a very diverse group of extinct marine arthropods. They first appeared in the fossil record in the Early Cambrian (521 million years ago) and went extinct during the Permian mass extinction (250 million years ago). They were one of the most successful of the early animals on our planet with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
