Abstract
The project is a basic micropaleontological research. The study on the early planktonic foraminifers (calcareous single-celled animals) is very important from the taxonomical stratigraphical, paleoecological and paleontographical points of view. With their help, we can get answer what kind of environmental changes forced the evolutional development of the foraminifers, namely a part of them changed from to the benthic to the planktonic life of mode. Several theories were born to explain this dramatical change. There are differences, but all of them agree about that these forms appeared only in the uppermost Bajocian (Middle Jurassic), they were small with low diversity and they had subordinate role in the fauna. All of these statements were refuted in my 5 previous studies on the Lower and Middle Jurassic material from Hungary (Görög, 1994; Wernli, & Görög, 1998, 1999, 2000; Görög & Wernli, 2002). Using a special extracting method, acetolysis I could examine the microfauna of the hard, unwashable rocks of the Tethyan Realm (oceanic development), from where practically there were no valued data about this group. Previously lots of protoglobigerinids were described from the Jurassic of the epicontinental area. Now I have possibility to compare the faunas from these different paleogeographical areas in space and in time.
