Gennaeocrinus Crinoid Calyx Fossil

Here is a picture of a rare crinoid calyx fossil embedded in matrix. It appears to be a Gennaeocrinus kentuckiensis (Shumard). The specimen was found in the Beechwood Limestone of Clark County, Indiana, USA. This fossil dates to the Middle Devonian Period (Givetian).

Thanks to Kenny for showing me the fossil.
