Recovered from the restricted-access Restoration Point Private Estate on Bainbridge Island, Washington, this specimen originates from the Blakeley Formation (Oligocene Epoch, ~30 Million Years Old). This unique locality is situated within the Seattle Fault Zone, where intense tectonic pressure and mineral-rich marine strata have resulted in exceptional high-density mineralization. These conditions have produced robust, silicified fossils that are world-renowned for their structural integrity and the unique reactive properties of the preserved biological material.Specimen Overview
• Weight: 144 Grams
• Dimensions: ~3” Length (Comparable to US Quarter for scale)
• Color: High-Contrast Olive Green & Obsidian Black
• Luster: High Natural Luster (Dry)
• Mineralization: Full Silicified/Agatized Replacement
Technical Description
This is a premier \"Matrix-Free\" specimen, a rare find where the original host rock has naturally weathered away, leaving the fully mineralized body of the crab entirely exposed. It is a 360-degree biological record preserved in stone.
Anatomical & Aesthetic Features:
• Full Body Integrity: The specimen represents the complete animal, showing the distinctive high-domed carapace and structural margins.
• Exceptional Mineralization: The surface is remarkably smooth with a tight, glassy grain. Unlike common fossils, this piece maintains a vibrant, deep luster even when bone-dry.
• Signature Coloration: Features a stunning \"camo\" pattern of sage and olive greens—a specific geochemical signature of the Blakeley Formation\'s unique mineral environment.
The \"Clean Reveal\" Advantage
As a naturally weathered-out specimen, this piece is 100% Tool-Free.
• Zero Damage: No air-scribes, chemicals, or abrasives have touched this surface. It has been polished only by the tides of the Puget Sound over millions of years.
• Current State: Hand-cleaned with only hot water and a soft brush. It is chemically pure with no oils or stabilizers.
Collector’s Note
This 144g Olive Crab is a \"Masterpiece\" grade specimen. While nodules are found occasionally, a fully exposed, lustrous, and color-rich crab of this caliber is a rare outlier. It is a world-class example of the \"Gem-Fossils\" produced by the Seattle Fault Zone and a cornerstone piece for any serious Pacific Northwest c
