Aulopora on Orthospirifer Brachiopod

One of the easier fossils to prep with sand abrasion cleaning are specimens from the Silver Creek Member, North Vernon Limestone of Clark County, Indiana USA.  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!

Metopolichas breviceps Trilobite

Recently, I read on the Fossil Forum about a find in the Waldron Shale of a Metopolichas breviceps trilobite pygidium.  It reminded me of something Kenny found in southern Indiana as well.  He sent me the pictures of a cephalon and pygidium of the type of Silurian fossil.  It was found in Clark County, Indiana.  Be advised this trilobite was once known as the Lichas breviceps.

Note on the picture below. The trilobite is mixed into what appears to be a Lichenalia concentrica bryozoan.
