A large trilobite fossil is set in a stable matrix. The piece has a flat back which allows it to be displayed as a plaque.
Trilobites, which are an extinct form of marine life, lived 520 million years ago in approximately the mid Cambrian period. These many legged arthropods with body armour roamed the sandy bottoms of the seas and coral reefs in search of food for over 270 million years before becoming extinct. They were one of the earliest invertebrates on Earth.
