Pair of Pedinopariops Trilobites - Mrakib, Morocco

This is a beautifully presented pair of Pedinopariops vagabundus trilobites quarried near Mrakib, Morocco. There are two of these large phacopids in natural association. One is outstretched with it's head tucked and would be about 2.8" long if outstretched. The second is enrolled and would be close to 3.5" if outstretched. They are nicely prepared and both have good eye facets.

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.
