Here is a very interesting Coal Age plant. This is Sphenophyllum sp. from the Pennsylvanian of Pennsylvania. This unusual fossil plant consisted of a slender stem bearing whorls of wedge-shaped leaves. This plant became extinct at the end of the Pennsylvanian. This Sphenophyllum exhibits excellent detail. There are many whorls of leaves present on this frond. The slender stem is easily seen, and the individual, spatulate leaves are clearly defined. The fossil plant has a distinct, shiny-white coloration and contrasts wonderfully with the black shale. This is a very collectible example of this unique fossil plant.
