Unidentified Horn Coral Fossil

This picture shows an unidentified horn coral fossil. The small bumps on across the fossil might be the remains of some type of holdfast the creature used to anchor itself to the seabed. It was found in the Glen Dean Member of Grayson County, Kentucky, USA. The fossil dates to the Mississippian Period. It is small about 1.7 cm tall.

Thanks to Kenny for the image.

Reminds me of Lophophyillidium spinosum but that is a Pennsylvanian species.

The Glen Dean of crane Indiana document lists a Triplophyllites(Zaphrentis) spinulosis coral.
