Unidentified Horn Coral

This horn coral was found in Clark County, Indiana. It is of the Devonian Period and I am still try to figure out its identification.

UPDATE (2021): This could be a Bordenia knappi (Hall, 1882). Found in the Speed Limestone of Clark County, Indiana USA.

 

 

Indiana Horn Coral - Heliophyllum

Searching through horn corals I have collected in 2009 I hope to find a Bordenia knappi (Hall, 1882).  Instead I continue to identify Heliophyllum sp. (Hall) horn coral fossils. Here are some images of 4 more that seemed picture worthy.

These horn coral fossils were found Jeffersonville or Beechwood Limestone of Clark County, Indiana. They existed in the Devonian Period.

Here is a budding horn coral emerging from a parent horn coral.

 

 

A Paleozoic Christmas Greeting

Merry Christmas to all and may Santa bring you lots of nice fossils!

For the curious this image is a composite of four different fossils.  The main tree body is an unidentified Devonian Period horn coral from the Jeffersonville Limestone of Clark County, Indina.  The tree trunk is a unidentified crinoid stem from Lake Cumberland, Kentucky (Mississippian Period, Fort Payne Formation).  The ornaments are Pentremites blastoids from Crawford County, Indiana (Haney Formation(?) and Mississippian Period).  The star is a crinoid stem cross section from the same area the blastoids were found at.  Artistic license was exercised with the fossil colors and illumination.
