A Carboniferous forest of Midwestern North America 350 million years ago featuring vascular, arborescent (tree-like) plants of the species Lepidodendron aculeatum (resembling feather dusters on long sticks), spore-bearing, arborescent plants of the species Sigillaria scutellata (resembling toilet bowl brushes), Asteroxylon mackiei (at this scale may be mistaken for grass), and ferns. Some Lepidodendron grew as tall as 150 feet.
