Turitella Agate (Tumbled)
Courtesy of geology.com:
Turritella Agate is the popular name used for a brown, translucent to semi-transparent, fossiliferous agate found in the Green River Formation of Wyoming. It is very easy to recognize because it contains large fossil snails that stand out in a white-to-tan color that contrasts with the brownish agate.
This organic gem material was incorrectly named decades ago when the christener thought that the spectacular spiral-shaped gastropod (snail) fossilsentombed within the stone were members of the marine Turritella genus. That was a mistake. Instead, the fossils are of the freshwater snail, Elimia tenera, a member of the Pleuroceridae family.
