Nummulite Foraminifera Fossil

This foraminifera fossil is known as a Nummulites laevigatus?. It was found near Soissons, Aisne, France. The fossil dates to the Eocene Epoch (about 47 million years ago). This fossil originally just a smooth disk about the size of an American dime. Using a belt sander, the surface was taken off revealing more spiral chambers.

Thanks to Dave for this fossil.

UPDATE on 2020/02/15 added species name.
