Pennsylvanian fern plant fossils from eastern Pennsylvania anthracite coal mines. The ferns are preserved in the mineral pyrophyllite,
which sometimes gives them a crisp bold white or silver appearance. Pyrophyllite is a pyrite pseudomorph. Any orange or gold color was caused by
iron ores in the ground.
This collecting locality has now been closed and in the future these specimens will be harder to obtain
