2.4" Flying Ceratonurus Trilobite - Top Quality Prep

Flying Ceratonurus Trilobite - Top Quality Prep #213171

This is an incredible example of a rare, spiny Ceratonurus trilobite from the Lower Devonian of Morocco. This example has excellent shell quality, and all the long spines have been prepared free-standing. Both the head and the tail were slightly disarticulated and were moved back into position during preparation, but otherwise there is no 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: 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.
