Fossil trunk with exceptional preservation!! - Fossilised plant - Calamites (Stylocalamites) cistii (SCHLOTHEIM; BRONGNIART, 1828) - 117 mm - 47 mm (No Reserve Price)

Spectacular fossilized trunk of a horsetail. The preparation of the specimen was very laborious, preserving the finest details of the plant.
Calamites is a genus of tree-like Equisetophyta. These plants reached heights exceeding 20 meters and formed dense forests in marshy areas thanks to their clonal growth. Anatomically, they consisted of a hollow, erect trunk or stem, organized into nodes and internodes with secondary growth and xylem formed from a cambium. This stem had primary branches arranged in whorls along its entire length. Also arranged in whorls on the primary or secondary branches were the leaves and spore-forming strobilus-type fruiting bodies. The root system of Calamites was formed by an extensive network of prostrate rhizomes in the substrate with irregular branching, possessing small-diameter rootlets that developed profusely at the nodes and, sometimes, at the base of the stems. The preparation of the specimen was very laborious, preserving the finest details of the plant.
Calamites (Stylocalamites) cistii can be identified by the fact that the internodes are longer than they are wide. There are no branch scars.
Plastic support included.
