Spiny Cyphaspis Trilobite With Morocops - Top Quality Preparation

This is a well prepared association of two different types of trilobites from Ofaten, Morocco. There is a spiny Cyphaspis with a very bumpy glabella, next to a prone Morocops. The Cyphaspis is is about 1.5" long including spines and the Morocops is 2". Excellent eye facet preservation on the Morocops with an exposed glabella on the underside of its head. Total shell restoration is 1-2% along repaired cracks.

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.
