Pyritized Triarthrus Trilobites With Legs & Brittle Star - New York
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.
These are very detailed trilobite (Triarthrus eatoni) specimens with preserved legs and antennae. Two are in excellent condition, with the third being partial. They measure approximately .43", .42", and .41", and are located on a 5.8 x 4.05" slab of shale. What really stands out on this specimen is the rare, 1.22" wide brittle star (Ophiuroidea sp.) fossil that has yet to have a described species.
Included with your specimen are printed copies of the cropped in photos seen above.
It comes with an acrylic display stand.

About Trilobites
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.
