Double Arctinurus Trilobite Plate - Middleport, New York

This is a natural double Arctinurus boltoni trilobite specimen from the famous Caleb's Quarry near Middleport, New York. Very few multiples of this rare Silurian lichid trilobite have been found over the years. Both specimens on this plate of over 4" long, with the overlying trilobite measuring 5.05", which is fairly large for the species.

Comes with a display stand.

There is restoration to the pygidium of the overlying trilobite, along with gap fill restoration along repaired cracks where the rock split during collection.

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.
