Bargain, 1.5" Crotalocephalus (Not Gibbus) - Uncommon Species

Do not confuse this with the common trilobite Crotalocephalina gibbus frequently seen for sale. This is a different genus that comes from the area near Lghaft, Morocco. The pygidial (tail) spines are distinctly different.

This is a bargain specimen as the preparation is pretty rough leaving a lot of scratches on the shell. There is some patches of shell restoration.

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 described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left a excellent fossil record.
