6.5" Silurian Trilobite (Trimerus) Fossil - New York

This is a 6.5" 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. There is some substantial shell restoration, primarily on its head, but it looks like about 25% in total. 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.

About Trilobites

Trilobites are an extinct class of marine arthropods that thrived for nearly 270 million years, from the early Cambrian to the end of the Permian period (around 521 to 252 million years ago). They are one of the most successful and diverse groups in the history of life, with over 25,000 described species spanning a wide range of sizes, shapes, and ecological niches. Known for their distinctive, segmented exoskeletons, trilobites provide invaluable insights into the evolutionary history of arthropods and the dynamics of ancient marine ecosystems.
