Aulopora on Orthospirifer Brachiopod


One of the easier fossils to prep with sand abrasion cleaning are specimens from the Silver Creek Limestone of Clark County, Indiana.  I believe it is this layer of limestone that the county's large concrete plant uses to manufacture product.  This fossil is the Orthospirifer brachiopod and it has a nice colony of Aulopora coral growing on it.  The brachiopod and coral lived in the Middle Devonian Period.

Thanks to Kenny for cleaning this one up for me!
