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 beautiful chunk is an excellent display specimen or can be used in lapidary to create jewelry.
Please see all of the photos. Thanks.
