Formation: Edwardsville Formation
Location: Crawfordsville, Indiana
Size: Gastropod is 1 inch long
This is a great specimen of a Platyceras gastropod from the Edwardsville Formation of Indiana. This gastropod, in life, affixed itself to a living crinoid and fed off the excrement from the echinoderm. In doing so, it cleaned up the environment so the crinoid could keep living. The distinct fossil has great color and contrast and is well showcased on the semi-rectangular plate of matrix. This is a very nice gastropod specimen from the Mississippian of Indiana.
A Certificate of Authenticity from EXTINCTIONS is included with this specimen.
