Abstract
After the end-Permian biotic catastrophe, the recovery of the marine ecosystems was a complex and long-lasting process during the Early Triassic, whereas it accelerated in the Middle Triassic, when most animal groups showed definite radiation. The project is aimed at the taxonomy, and complex evaluation of the Middle Triassic Radiolaria, Ammonoidea, Bivalvia, Ostracoda and Brachiopoda. The core of our data base is the rich fossil material resulted from detailed collecting work in several Anisian and Ladinian sections of the Balaton Highland, what needs only some complementary sampling. The scope of the study will be extended to the well-known faunas of the Alpine-Mediterranean region. In order to reach a global (or at least Tethyan) picture, the international Paleobiology Database (PBDB) will also be used. The radiative evolution of the above animal groups showed various rates and patterns in the Middle Triassic. These will be evaluated in detail. The Mesozoic Marine Revolution comprises a series of complex paleobiological changes; from among these, the project will analyse the following items: 1. Infaunalization and the incipient eclipse of the sessile animal groups. 2. Adaptive responses to the diversification of marine predators (escalation). 3. Rapid diversification of the marine microplankton. The paleobiogeographical evaluation of the planktonic and nektonic groups (Radiolaria, Ammonoidea, Ostracoda) may contribute to the better knowledge of the paleogeography and paleooceanography of the Triassic Tethys.
