.9" Gerastos Trilobite Fossil - Well Prepared
This is a well prepared specimen of the proetid trilobite Gerastos granulosus from Issoumour, Morocco. It's very 3d with excellent shell detail.
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: over 25,000 species have been described, filling nearly every evolutionary niche. Due in large part to their hard exoskeletons (shells), they left an excellent fossil record.
