Two Ceratarges Spinosus Trilobite from Morocco (454.6 grams)
This is an extremely ornamented member of the trilobites' well-known and globally distributed Lichid family. These trilobites (two present) have adapted for extreme defensiveness. Their long genal appendages afford them controlled escape from the water column, and they used them to sink to the ocean floor mimicking falling organic debris to escape predators. The stalked eyes, which evolved several separate times in the trilobite lineage, afforded greater lookout ability through they still maintain their compound lenses. You will receive the exact object as in these photos. Certificate of Authenticity will be sent with purchase.
