Bargain, 2.7" Morocconites Trilobite - Ofaten, Morocco
Here is a bargain, 2.7" long specimen of Morocconites malladoides from Ofaten, Morocco. This species typically has a long rostrum off of the front of it's head, but it's stunted in this specimen. Whether this represents a different species or just a growth abnormality I don't know. Clear eye facets in both eyes. There is some scratches on the shell from preparation, hence the lower price.
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.
