Description: Specimen: Trunk of rarer coal age lycopod Bergeria dilatata Lindey & HuttonLocality: Poland, GZW Upper Silesia Coal Basin, Stratigraphy: Lower Carboniferous, Mississipian – Serpukhovian - Namurian AAge: ca. 330 myo Matrix dimensions: ca. 7,5 x 4,5 x 2,0 cm Young Lepidodenron cousine, rarer lycopod: Bergeria dilatata Lindey & Hutton trunk preserved in siderite matrix. Bergeria dilatata Lindey & Hutton is an extinct genus of primitive, vascular, arborescent (tree-like) plant related to the Lycopsids (club mosses). It was part of the coal forest flora. They sometimes reached heights of over 30 metres (100 ft), and the trunks were often over 1 m (3.3 ft) in diameter, and thrived during the Carboniferous period. Sometimes called "giant club mosses", this is actually not correct as they are actually closer to quillworts than to club mosses. The closely packed diamond-shaped leaf scars left on the trunk and stems as the plant grew provide some of the most interesting and common fossils in Carboniferous shales and accompanying coal deposits. These fossils look much like tire tracks or alligator skin. The scars, or leaf cushions, were composed of green photosynthetic tissue, evidenced by the cuticle covering and being dotted with stomata, microscopic pores through which carbon dioxide from the air diffuses into plants.
