.4 Inch Triarthrus With Preserved Legs

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 specimen is 10mm (.4 inches) in length, preserved partially on it's side exposing great leg preservation. Preparation of these soft bodied specimens is an immensely time consuming task. It is done under high magnification using extremely low pressure air abrasion. A specimen like this would have taken several hours to complete.
