Lepidodendron

Lepidodendron is one of the most representative trees in ancient times, which has been extinct among the Lycopodia (fossils). It has woody ferns. It appeared in the Carboniferous, arbor-like, and co-propagated with many tropical swamp plants to form forests in the tropical swamp area. It is an important raw material for the formation of coal in the Carboniferous, and it is also one of the rations of ancient vegetarian animals.
