Alethopteris - Pennsylvanian Plant

This fossil is not from the Louisville area but I think my cousin bought it at the Falls of the Ohio fossil festival (http://www.fallsoftheohio.org/fossil_festival.shtml) which is in the Louisville area.

According to its label, it is a Alethopteris from the Pennsylvanian Period. It was found in the Strangter formation in Ottawa, Kansas.
