This is a large fossil seed fern from the Pennsylvanian of Missouri. The seed fern has been preserved in a siderite concretion. Both halves (part and counterpart) of the nodule are present. The dark color of the seed fern contrasts nicely with the orangish concretion. The fossil exhibits fine detail, and the individual frondlets are very well defined. This is a wonderful specimen of a large fossil seed fern from the Coal Age of the Midwestern United States.
