Photos bt Musette Scott.

Humboldt County locals Musette and Vaughn Scott happened upon something very strange while collecting rocks below some recently slid out bluffs at Guthrie Creek yesterday.

“We were collecting rocks and my hubby found this laying on top of the sand near the water,” Musette Scott wrote on Facebook. “It measures approx. 1 1/4” - 1 1/2” diameter. Hubby thinks it may be a fossilized snail body. I think it’s a handmade necklace made out of the amazing clay out there and fired in a fire pit. WHAT DO YOU THINK IT IS? Please HELP!!”

A couple of local biologists responded to Facebook query saying it might be the fossilized slime casing of an ancient sea snail, or maybe sediment that formed inside an empty shell. Other commenters are convinced it’s poo. But no one seems to know for sure.

So whada ya think Humboldt? Fossilized snail goo? Dino droppings? The remnants of a very proud caveman? LoCO Challenge starts now.
