Beautiful and carefully displayable trilobite. This is a beautiful specimen from the Devonian period 410 million years ago. Zlichovaspis Rugosa from the Devonian of Morocco. This amazing trilobite specimen has been meticulously prepared by paleontologist in Morocco. Beautiful detail in the head eye and back. The trilobite has a full back restoration part of the left spine is missing.
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).
