Double Devonian Coral Fossil

This image is of two coral fossils. One is growing upon another, they appear to be Aulocystis frutecticosa on Thamnoptychia vermiculosa. They were found in the Beechwood Limestone of Clark County Indiana, USA. These fossils date to the Devonian Period. Thanks to Kenny for images.
