6.2" Silurian Trilobite (Trimerus) Fossil - New York
This is a 6.2" long specimen of an uncommon Trimerus delphinocephalus trilobite from the Rochester Shale of New York. It is nicely centered on a solid piece of shale. It looks like it has about 15-20% shell restoration. This is par for the course on many Rochester shale trilobites whose shell is often damaged due to water in between the shale layers.
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: 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.
