.55" Pyritized Triarthrus Trilobite With Appendages - Near Perfect!

The localities that preserve trilobites with soft bodied preservation can probably be counted on one hand. One of these localities is where this specimen is from, the historic Beecher's trilobite beds in the Lorraine Group of New York. 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, dorsally preserved specimen with legs and antennae. It measures approximately .55" and is located on a 2.7 x 2.5" slab of shale. It comes with an acrylic display stand.

Included with your specimen is a printed copy of the cropped in photo seen above.
