2" Fossil Crab (Potamon) Preserved in Travertine - Turkey

 
 
 
 
This is a spectacular fossil freshwater crab (Potamon sp.) preserved in travertine from the Denizli Basin in Southwest Turkey. The crab itself is 2" wide (including legs) and exhibits very detailed, 3d preservation. It's preserved as a three-dimensional outer cast within a natural cavity in white travertine. The fossil is covered by an inorganic film of calcium carbonate.

Travertine is a type of limestone that forms around mineral springs. It is often quarried for use as a building material, and that is how these crabs were discovered. They are found when hollow voids are cut into while sawing blocks of travertine. The travertine deposits in the Denizli Basin are Pleistocene in age, having been formed within the past 400,000 years.
