.85" Pyritized Triarthrus Trilobite With Appendages - New York

The localities that preserve trilobites with soft bodied preservation can probably be counted on one hand. One of these localities is the historic Beecher's beds in the Lorraine Group of NY. Less than a decade ago a new locality was discovered a short distance away that has produced amazing, soft bodied preservation of trilobites and other organisms. Because of the rapid burial of the trilobites, in an anoxic environment the soft body parts were replaced by pyrite preserving details not typically seen.

This is a very detailed, ventrally preserved specimen with legs and partial antennae. It measures approximately .85" and is located on a 4.2 x 3.7" slab of shale.
