2.5" Morocconites Trilobite Fossil - Morocco
This is a 2.5" specimen of Morocconites malladoides. The genus has a distinctive pointed rostrum coming off the front of its head. Much of the limestone has been removed from around it, leaving it perched on a pedestal of rock.
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.
