Trilobites thrived throughout the Paleozoic world, comprising one of the earliest known groups of arthropods. They flourished to over 600 species at their zenith, including many with exotic exoskeletons and unique feeding strategies. They are probably most closely related to modern horseshoe crabs.
Though the Cambrian (521 mya) marks the appearance of trilobites in the fossil record, they were already highly diverse. They continued to proliferate until their decline in the Devonian and eventual disappearance in the Permian mass extinction (250 mya).
This is a Pedinopariops (Hypsipariops) vagabundus from Mrakib, Morocco. The Trilobite has been partially removed from the host rock which serves as a base for display.
