1.05" Acastoides Trilobite - Foum Zguid, Morocco

This is a nice, 1.05" long example of the small phacopid trilobite Acastoides zguilmensis from the Timrhanrhart Formation south of Foum Zguid, Morocco. There is some shell restoration on the left side of the head.

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.
