2.7" Arctinurus Trilobite Head - Classic New York Trilobite

This is a partial head of an Arctinurus trilobite fossil from Caleb's Quarry near Middleport, New York. Arctinurus was a large lichid trilobite, which is highly sought after by collectors.

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.
