Catalog Number: CG-0028
The fossil Amphiscapha appears readily within shale locally. Buried at an angle different from the plane the shale sheared from, this specimen is a bit unique. Only the raised rim was visible initially. Using precision tweezers, I utilized the sharp metal ends and a microscope to slowly reveal the rest of the fossil.
There are several species of Amphiscapha, and I can’t easily identify this one. The species being Subrugosus is likely, but I am not sure. The raised ridge and swirl pattern matches, and it has been found in Pennsylvania.
