Neuropteris Plant Fossil

These pictures of fossilized plants found in St. Clair, Pennsylvania. They grew in the Pennsylvanian or Late Carboniferous Period. Geologically they can be located in the Llewellyn Formation.

I think the plant in these pictures is called the Neuropteris.

Indiana Devonian Wood

Devonian wood pieces probably from a Callixylon log. They were found in New Albany Shale in Clark County, Indiana. The wood has been coalified or vitrinized by heat and pressure over time.

Aulocystis Coral

Two pictures of the same fossil that is some type of Aulocystis coral found in Clark County, Indiana. It is from the Devonian Period and I believe I was in the Beechwood Limestone when I found it. This fossil is relatively small and could fit in a 2 cm cube.

This particular fossil might be a Aulocystis frutectosa described by W.J. Davis in 1887 (Kentucky fossil corals, a monograph of the fossil corals of the Silurian and Devonian rocks of Kentucky, Part 2).
