3" Zlichovaspis Trilobite With Two Reedops - Morocco
This is a really cool trilobite association from Atchana, Morocco. There is a 3" long Zlichovaspis associated with a pair of Reedops. The surrounding limestone has been removed to create an aesthetic display piece of the three trilobites. Nice eye facet preservation in all of the trilobites.
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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
