Exquisite Enrolled Metacanthina Trilobite - Lghaft, Morocco

This is one of those trilobite specimens that make you say, wow! It is an exquisitely prepared, enrolled Metacanthina issoumourensis collected near Lghaft, Morocco. All of the surrounding limestone as been carefully removed leaving it supported by just its spines.

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.
