What is Turritella Agate?
Turritella Agate is an agate filled with fossils, found in the Green River Formation of Wyoming. The white imprints mark the fossilized snails that contrast with the dark brown stone of the agate. It is poorly named; scientists first thought that the fossilized snails within were of the genus Turritella, but this was later disproven.
