Modiomorpha Clam Fossil

Some images of a Modiomorpha clam fossil found in the Mahantango Formation, Pennsylvania. This pelecypod existed in the Devonian Period. Great line detail in this casting. I have only found one of these in the Jeffersonville Limestone of Clark County, Indiana.

Thank you to Dave for providing the images for today's post.
