4.1" Partial Trilobite (Trimerus) Fossil - New York

This is a partial specimen of an uncommon Trimerus delphinocephalus trilobite from the Rochester Shale of New York. If it wasn't missing its back half it would have been over 6" long.

Comes with an acrylic display stand.

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 with over 25k currently described species, filling nearly every evolutionary niche. Due in large part to a hard exoskeleton (shell), they left an excellent fossil record.
