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

Asprosaurus () is an extinct genus of anguimorph lizard from the Late Cretaceous (Campanian) of South Korea. The genus contains a single species, A. bibongriensis, which is the first Mesozoic lizard to have been discovered on the Korean peninsula. Initially classified as a possible monstersaurian, Asprosaurus has been subsequently suggested to be a probable mosasauroid, an extinct group of marine lizards during the Late Cretaceous.
