Hunting for mass extinction #3

The end-Triassic mass extinction event (201.5 million years ago) was one of the five largest mass extinctions during the last 541 million years of our earth’s history. It is marked by major decrease in biodiversity (>80%) primarily in the marine realm. The biotic catastrophe coincides with the initial break-up of the supercontinent Pangea. 

In the “Hunting for Mass extinction” series, we follow the multidisciplinary team of researchers from GEUS, IGN and AU in their search for answers regarding the causes and consequences of the end-Triassic mass extinction event. 

In this episode the team documents all the sections of the sediment core with photography. In doing so the team ensures that the true colours and structure of the fresh sediment will be saved for future investigations.
