6.1" Pennsylvanian Fossil Horsetail (Sphenophyllum?) Plate - Kentucky

This is a beautiful fossil flora plate that contains horsetail fossils. This plate was collected from the Breathitt Formation of Leslie County, Kentucky. It comes from the Late Carboniferous, Pennsylvanian aged forests that formed the coal shales of Kentucky and Ohio.

The preservation detail isn't the greatest, making this specimen difficult to identify. It resembles the species Sphenophyllum myriophyllum, as well as a Asterophyllites sp.. Based on the associated Sphenophyllum whorl, I'm leaning towards this specimen being of the species Sphenophyllum myriophyllum.

It comes with an acrylic display stand.
