The opal snake head cast. It was cat scanned for bones, negative as a cast is generally opal skin to skin. Center is straight up POC and outside coating is contra luz with POC.
The chin feelers location for a Western Shovel head snake would have been above to top of the opalization layer. Definitely play of color but not some 5 bright super gem. In glycerin but the body segment i have is dry and never been stored wet. Its not crazed. Asking $25,000 US to buy it now. Comes with documentation & provenance, serious inquiry only please. No Im not making a movie. That would be the privilege of the buyer to do or i may smash it for an NFT like some Banksy person.
Nobody else has ever photographed it or certified it was just a rock despite it being offered for id & recording by Berkeley. Which is who said it was a snake and not a lizard cast, but would not certify that….. ie none of my emails were answered with a I can do paleo herpetology for free or for a fee. Why not? Its one of a kind whether you believe it yet or not. Can you tell Im still seeking an expert?
