Megastrophia (Silver Creek Limestone)

This brachiopod fossil is a nice find in that is over 5 cm in width.  It appears to be intact though needs to be cleaned with sand abrasive cleaning. Usually only the top half is found of this genus, Megastrophia.  These types of brachiopods might be one of the largest found in the Devonian layers around southern Indiana.

Fossil was found in the Silver Creek Member of the North Vernon Limestone of Clark County, Indiana, USA. This layer dates to the Devonian Period (Eifelian).

Hopefully, a posting of it cleaned up can be presented...
