Fossil Seed Fern
Age: Pennsylvanian
Formation: Carbondale Formation

Here is a nice Pennsylvanian plant fossil. It is a Seed Fern from the famous Mazon Creek deposits of Illinois. This very distinct Seed Fern is well preserved in a siderite concretion. Both halves of the concretion are present, so both part and counterpart are intact. The fossil plant exhibits wonderful detail. The central stem is clearly defined, and the individual leaflets are beautifully displayed. The fossil has great, natural color and contrast. This is a very aesthetic example of a fossil Seed Fern from the Coal Age.
