Orbitoplax Fossil Crab Gem from Oregon

High resolution image above, other images below

Description: This is very well preserved specimen of Orbitoplax. All ten appendages are present. Even the left eyestalk has been preserved. The specimen exhibits an off white color set off nicely against the light gray background concretion. It was discovered by cracking the concretion in which it was residing for so many millions of years. The concretion was then re-glued and painstakingly curated with air abrasion. (The positive never splits cleanly from the negative in these concretions.) Many hours of skilled preparation were required to render this gem in concretion.
