A triász és a jura időszak határán lezajlott globális krízis és annak nyomai magyarországi rétegsorokban

The mass extinction at the end of the Triassic Period was one of the largest extinction events in the Phanerozoic and it was the result of a global environmental crisis. In connection with this, the last two decades have seen increasing research efforts to gain more knowledge and thus a better understanding of this event. These efforts have included detailed studies of numerous stratigraphic sections worldwide. The review presented here attempts to summarize the major results of multi-faceted international research on the stratigraphic and fossil record of the end-Triassic event, discussing proposed cause-and-effect relationships and possible scenarios. In addition, there is also an overview of studies  made  in  recent  decades  on  the  Triassic-Jurassic  boundary  sections  in  Hungary,  with  an  emphasis  on  their relevance to global research into the Triassic-Jurassic boundary.
