Fossil mosses and a beetle. (A) Stem and leaves of the semiaquatic moss Drepanocladus longifolius (Mitt.) Broth. ex. Paris. (B) Enlargement of stem and leaves. The diagnostic features of the fossils are long lanceolate leaves up to 2.2 mm in length, strong percurrent or excurrent costae, elongate lamina cells, and enlarged alar cells that are quadrate-rectangular across the leaf base. Short, broad pseudoparaphyllia or juvenile leaves with single, long, sharp apical cells are visible in some leaf axils, and the stem has thick-walled outer cells and a central strand with thin-walled cells. (C) Stem and leaves of an unknown species of a terrestrial haplolepidous moss with large isodiametric cells. (D) Illustration of the base of the left elytron of a beetle.
