Research Paper


Miaolingian rocks of the Delitzsch–Torgau–Doberlug Syncline yield Helcionelloida and Hyolitha that are otherwise poorly known from this stratigraphical interval in Central Europe. The two faunal intervals from the lower part of the Wuliuan and the lower part of the Drumian Stage include the helcionelloid genera Helcionella, Marocella and Leptostega, and at least nine different species of hyoliths, mostly preserved in a manner that does not permit precise determination, but they distinctly broaden the paragon of the West Gondwana molluscan faunas and revise earlier reports on the faunal spectrum. A new species of Aladraco is introduced as A. kirchhainensis sp. nov.

Study and loan of specimens was made possible by Dr. Angela Ehling (collections of the Bundesanstalt für Geowissenschaften und Rohstoffe, Berlin-Spandau), which is gratefully acknowledged. P. Yu. Parkhaev (Moscow) and an anonymous reviewer provided helpful comments and suggestions on the manuscript. The study was made possible by research grants of the Deutsche Forschungsgemeinschaft (DFG) to the senior author (grant GE 549/22-1 to G.G.).
