Prehistoric trees

Lepidodendron, from Ancient Greek λεπίς (lepís), meaning "scale", and δένδρον (déndron), meaning "tree", is an extinct genus of primitive lycopodian vascular plants belonging to the order Lepidodendrales. It is well preserved and common in the fossil record. Like other Lepidodendrales, species of Lepidodendron grew as large-tree-like plants in wetland coal forest environments. They sometimes reached heights of , and the trunks were often over in diameter. They are often known as "scale trees", due to their bark having been covered in diamond-shaped leaf-bases, from which leaves grew during ear

Sigillaria is a genus of extinct, spore-bearing, arborescent lycophyte, known from the Carboniferous and Permian periods. It is related to the more famous Lepidodendron, and more distantly to modern quillworts.
