Lund, J.J. and Ecke, H.-H., 1988; Dinoflagellate cyst stratigraphy applied to the Middle to Late Jurassic of the Regensburg-Passau area. Bul. Centr. Rech. Expl.-Prod. Elf-Aquitaine 12-1 pp.345-359 pl.3 The water exploration wells Buchberg 3 and Winzer and the research well Ortenburg 1 from the area between Regensburg and Passau, Bavaria. were studied palynologically Both preparation methods with and without use of hydrofluoric acid were employed successfully. Spores and pollen and especially dinoflagellate cysts date the quantltatlvely documented microfloras to be of Aalenian, Early to Middle Bajocian. Late Bajocian to Callovian and (Middle) Oxfordian age Reworked Carboni- ferous, Late Visean to Early Namurian spores were also present. A new species of Dinoflagellate cyst, Ambonosphaera bavarica and a new combination of a spore, Skarbysporltes crassexinus are proposed. The palynological datings mentioned indicate that the Jurassic marine transgres- sion represents an onlap sequence being oldest in the NW (Buchberg 3) and youngest In the SE (Ortenburg 1).
