This is a 2 inch ERYMA modestiforme, Lobster- like decapod crustacean from the famous Solnhofen Limestone in Eichstadt, Germany.
The Solnhofen Limestone is a lithographic limestone that is known as a Jurassic Lagerstatte. It has preserved a rare assemblage of organisms to include fish, plants, insects and including the famous Archaeopteryx. The most famous of all the fossils of the Solnhofen Limestone is the early feathered dinosaur. The Solnhofen beds of Germany are found near Eichstadt in the German State of Bavaria.
During the Jurassic this area was located at the edge of the Tethys Sea. This included shallow seas and lagoons whose salinity varied throughout time. At times so high as to not sustain life. The depths of the lagoons were often low on oxygen and as such creatures and anything that would become a fossils would not be scavenged by other creatures. They would die, or wash in and be covered by a soft fine grained mud silt.
These areas as they fossilized created a fine grained limestone that was used for making lithographic plates.
The specimen is 2 inches long and sits on a cream colored matrix 5 1/4 x 5 1/2 inches square. This specimen is complete with claws and antenna. The body is slightly sunken inn to the matrix and the claws are detailed.
This is a spectacular example of an
