The Horn Coral Siphonophrentis elongata

Besides finding Halysites in the Silurian layer I also come across segments of a species of horn coral that was huge. This is a smaller segment that measures about 7 cm in diameter. It is from the Devonian period and was called Siphonophrentis elongata (Rafenesque & Clifford, 1820).  Found in central Jefferson County, Louisville, Kentucky USA. This fossil is found in the Jeffersonville Limestone.
