Lepidostrobus sp.
Age: Pennsylvanian
Formation: Cherokee Series
Location: Pella, Iowa
Size: Cone is almost 3.6" long
Here is a rare cone from the Lepidodendron tree. This is Lepidostrobus sp. from the Pennsylvanian of Iowa. The cone of this tree consisted of a central stalk crowded with spirally arranged bracts, the upper surface of each bearing a single spore case. This large cone exhibits nice form and fine detail. This highly uncommon plant fossil is well presented on the natural plate of matrix that also contains an impression of Lepidodendron bark. The dark brown fossils contrast nicely with the light-colored sandstone. This is a fine specimen of this unusual cone from the Coal Age.
