1.8" Metascutellum Trilobite - Very Pustulose With Axial Spines
This is a nicely prepared, 1.85" long, Metascutellum trilobite from Ofaten, Morocco. Excellent shell detail including thousands of tiny eye facets are present. There is a tiny spine on each axial ring in this species, as well as spines above the eyes. There is about 3-5% shell restoration on this specimen, mainly where the repaired crack runs thorough the tail.
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.
