Cluster Nine Smooth Shelled Gerastos Trilobites - Mrakib, Morocco
This is a very aesthetic cluster of nice Gerastos trilobites from Mrakib, Morocco. This species of gerastos is a smooth head as opposed to the much more commonly seen Gerastos granulosus whose head is covered in small bumps. I had this piece in my personal collection for a few years and just decided to part with it.
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.
