.9" Rare Proetid Trilobite (Tropidocoryphe) - Issoumour, Morocco
This is a fairly rare type of proetid trilobite (Tropidocoryphe) from Jebel Issoumour, Morocco. This is an excellent example of the genus which is about average size at .9" long. It's nicely inflated and prepared. This is only the third example of the genus I've had for sale and definitely the best specimen.
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.
