Two Asaphid Trilobites (One Dorsal, One Ventral) - Taouz, Morocco

This is a pair of large, Ordovician, Asaphid trilobites collected near Taouz, Morocco. There is a nicely inflated, 4.9" long specimen naturally associated with a 3.7" long ventral specimen. The hypostome (mouth plate) has been exposed on the ventral example. Only a small amount of restoration on the genal spines on the dorsal trilobite.

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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
