2.7" 3D Fossil Crab (Pulalius) In Concretion - Washington

This is a 2.7" wide fossil crab (Pulalius vulgaris) from Southwest Washington. These crabs are found within hard concretions (a mass of rock that forms around organic manner) which must be broken open to find the crab. The crab must then be prepared from the hard concretion using air tools, a very time consuming process.

This one is nicely prepared and comes with an acrylic display stand.
