This custom cut Turritella cabochon is just layered with fossils and has a great central fossil.
Turritella Agate – Location – Wamsutter, Wyoming. This material comes from the Green River Formation (encompasses southwestern Wyoming, northeastern Utah, and northwestern Colorado). It is very easy to recognize because it contains large fossil snails (spiral shaped pelecypods) that stand out in a white-to-tan color that contrasts with the brownish agate. The agate was formed from layers deposited in a series of ancient freshwater lakes that geologists call Lake Gosiute and Lake Uinta, in the early and middle parts of the Eocene Epoch, between around 53 and 42 million years ago. The shells have actually been identified as Oxtrema and not Turritella.
