Abstract Brenner, W., 1988; Dinoflagellaten aus dem Unteren Malm (Oberer Jura) von S³dddeutschland; Morphologie, Íkologie, Stratigraphie. T³binger Mikropalõontologische Mitteilungen, Nr. 6. Abstract The lower Malm (Oxfordian to lower Kimmeridgian) of southern Germany contains rich and diversified dinoflagellate assemblages. In addition to samples collected from surface outcrops the material of Klement (1960) are revised. Lost holotypes are replaced with lectotypes. and if necessary redescribed. Based on morphological observations, the dinoflagellate cyst genera Acanthaulax, Epiplosphaera und Systematophora have been emended. Lithodinia arcanitabulata n. sp., Scriniodinium bucinatum bucinatum n. sp. n. subsp., Scriniodinium bucinatum labyrinthum n. sp. n. subsp. and Svstematophora varispinosa n. sp. are described as new. In the Upper Jurassic of southern Germany. the occurence of a large part of the dinoflagellate cysts is strongly facies-controlled. As in recent dinoflagellates, their distribution is much less governed by geographical latitude (provincialism) than by other systems (salinity, water depth, chemical composition of the water mass). In the Upper Jurassic, at least two systems could be recognized: ( l ) marl-limestone alternation (small cvcles, Milankovich cycles?) and (2) larger lithological units (Malm Alpha. Beta, Gamma). The "standard-zonation of dinoflagellates" published by Woollam and Riding (1983) for NW-Europe can also be applied in S-Germany. but a few modifications are necessary for ecological reasons. The dinoflagellates allow to correlate the Upper Jurassic of N-Europa and S-Germany independently from ammonites.
