Fossils from the Styrian Eisenwurzen would provide information about a gigantic mass extinction 233 million years ago.
There have been a number of climate catastrophes in Earth’s history. The one 233 million years ago, the “Carnic Crisis,” is now the focus of a new research project. For three years, an international team led by the Vienna Natural History Museum has been searching for fossils and core drilling in the Eisenwurzen near Großreifling in Styria.
Well-preserved fossils present
In the geological zone of the Reiflinger Basin, there are many particularly well-preserved animal species from this period, from which the researchers hope to gain new insights into the former mass extinction.
CO2 increase like today
At that time, increased volcanic activity would have led to a massive increase in CO2 in the atmosphere and, as a result, climate change. This would have wiped out nearly a third of marine animal species and facilitated the dinosaurs’ rise to become the dominant species on the planet.
Based on the findings of the project, conclusions can also be drawn about the effects of current climate change.
