This is a beautiful plant fossil. It is a striking plate of fossil fern fronds from Pennsylvania. This specimen is replaced with the mineral Pyrophyllite, which gives the fossil its stunning white color. The ferns have great detail and contrast beautifully with the black matrix plate. This is a distinct multiple example of fossil fern fronds from the Coal Age.
