Large, 4.3" Crotalocephalus Trilobite - Jorf, Morocco
This is a very large, 4.3" long Crotalocephalus trilobite (not to be confused with the common Crotacephalina) from Jorf, Morocco. These trilobites average under 2" in length and I've only seen a couple of monsters this size before.
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.
