Phaenocompsopogon pustulatus n.gen.n. sp., a calcareous alga from the lacustrine rotliegend of the Saar-Nahe Basin (SW-Germany)
Phaenocompsopogon pustulatus n. gen. n. sp. is a calcareous freshwater alga, probably of rhodophycean affinity. The fossils are mainly known from one locality in the Lower Permian of the Saar-Nahe Basin. The algal remains form a packstone in the Reckweilerhof-Bank of the Altenglan Formation. The simple thallus branches irregularly y-shaped and is covered with abundant pustules. An axial canal is characteristic, as are distinct cell features of an inner and outer cortex surrounding a structureless medulla. Most fossils are silicified and often three-dimensionally preserved. The algae lived in a wave-dominated environment, probably in offshore shallow water. The limited occurrence suggests sp…
Mikrofazies lakustriner Karbonathorizonte des Saar-Nahe-Beckens (Unterperm, Rotliegend, SW-Deutschland)
Die lakustrinen Karbonathorizonte der Lauterecken-Schichten im Saar-Nahe-Becken-Odenbach-Floz-Bank (OFB), Medard-Bank (MBK) und Wiesweiler-Bank (WIB)-sind mikrofaziell eindeutig voneinander zu unterscheiden und damit geeignete Leithorizonte. Die Karbonatbanke lassen sich differenzieren:
