Beautiful and carefully displayable trilobite. This is a beautiful specimen from the Devonian period 380 million years ago. Hollardops Mesocristata from the Devonian of Morocco. This amazing trilobite specimen has been meticulously prepared by paleontologist in Morocco. Just check out the amazing detail in the eye facets to see the quality in this trilobite. The trilobite has a full back restoration including an amazing lateral border spines.
Trilobite proliferated and 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).
