Fossils in the Snow

Some snow has finally accumulated in the Louisville, Kentucky area. It was maybe 1 cm or so and contributed to about 100 auto accidents. I am guessing the melted snow on the road froze and helped with all the accidents.

I decided to document the occasion of snow by photographing some of the fossils outside on the cleaning racks.  Devonian Period corals found in Clark County, Indiana.  On a side note, the Indiana State Museum has taken quite a few pictures of their fossil collection and posted it on their website.  Here is a sampling of horn corals pictures.

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.
