Major extinction events in the light of stable isotope compositions (860 KB, pdf)

Stable isotope studies on major extinction events (Permian-Triassic and Triassic-Jurassic) have been conducted in joint projects financed by the Hungarian Research Fund.

Co-operation partners: Dr. Janos Haas (Eötvös Loránd University & Hungarian Academy of Sciences, Geological, Geophysical & Space Science Research Group) and Dr. Jozsef Palfy (Hungarian Natural Science Museum & Hungarian Academy of Sciences, Paleontological Research Group)
