Colpodexylon deatsii Devonian Clubmoss Tree FossilsDescription: This plaque displays a pair of examples of the early Lycopsid land plant Colpodexylon as a positive and a negative. Each dimple on the stem represented a leaf attachment scar and was the source of the trivial name “scale tree”. The leaves themselves were trifurcate and bore a resemblance to pine needles arranged in a spiral around the trunk. They became a dominant plant type in the Carboniferous with the advent of the genus Lepidodendron. See my other offerings for Barawaganathia, thought to be the oldest of the Lycopods.
