Turritella Agate Fossil Specimens For SaleTurritella Agate

 
Rocks, Minerals, and FossilsTurritella Agate is actually a case of mistaken identity!  When this fossiliferous rock was first discovered in the famous Green River sedimentary deposits of Wyoming, the high-spired fossil shells were mistaken for those of marine gastropods (snails) in the genus Turritella.  By the time it was determined that they actually belong to a freshwater gastropod species called Elimia tenera, the incorrect name had already caught on among gemstone and lapidary enthusiasts.

Fifty million years ago, during the Eocene epoch, rains falling on the Rocky Mountains region filled many intermountain basins with freshwater lakes.  Abundant plants and algae grew around these lakes, creating  a rich food source for Elimia tenera.  When these prolific snails died and fell to the lake bottoms, great numbers of their shells were buried in the sediments washing down the mountain slopes.  Over time, silica-laden groundwater moved through the deposits and precipitated inside the empty shell cavities and the spaces between the shells, forming the dark-brown chalcedony that today is (inaccurately) called Turritella Agate.

Turritella Agate (or should we say, Elimia Agate?) polishes nicely and is often cut into cabochons or slabs for jewelry, belt buckles, and other lapidary craft items.  The specimens on this page fit smoothly into your hand, and are a fun, easy way to carry fossils in your pocket!
