Description

Lepidodendron sp. - fossil scale tree in micaceous sandstone in the Pennsylvanian of Ohio, USA. (geology hammer for scale) (photo by James Cheshire)

The nice, dark brown-colored plant fossil shown here is Lepidodendron, which was a large arborescent lycopod (= scale tree) common during the Pennsylvanian ("Age of Coal Swamps"). Lepidodendron is distinctive in having diamond-shaped leaf attachment scars on the tree trunk. The black-colored structure above the Lepidodendron is another fossil plant stem, preserved as a carbonized compression.

Classification: Plantae, Lycophyta, Lepidodendrales
