Abstract
The research is aimed to the interpretation of the important diversity peaks recorded in the Mesozoic (Triassic and Jurassic) marine formations of Hungary. There are several major diversity peaks shown by the most frequent and available marine fossil groups (Ammonoidea, Bivalvia, Brachiopoda). Some of these (e.g. Middle Triassic, Early Jurassic) are global phenomena and are connected to the end-Permian and end-Triassic mass extinctions. Other diversity peaks (Late Triassic, Middle and Late Jurassic) are local and may be explained by local environmental changes. The effects of the local environmental changes are superimposed on the global changes. The separation of these factors and their analysis and interpretation are among the main goals of our research.Hungary offers ample possibility for studies of this kind because: 1. The Mesozoic localities provided rich ammonoid, bivalve, brachiopod and other benthic fossil material with proper taxonomical data base, 2. The localities providing the rich fossil material belong to different terranes (Transdanubian Central Range - Pelsonia; Mecsek and Villány Mts. - Tisia) representing opposing continental margins of the Mesozoic Tethys and this help in distinguishing the local and global effects on changing diversity.
