Dinosaurs died because of an asteroid impact

The dinosaurs must have died because of an asteroid impact. Adobe Stock/ boscorelli Researchers disprove theory of volcanic eruption as reason for mass deaths / Mineralogists and planetologists of the University of Münster participating in worldwide study in "Science' Was it volcanic eruptions in western India or an asteroid impact that caused the death of dinosaurs and many other animal species 66 million years ago? Researchers have been discussing this since the 1980s. An international research team led by Yale University in the USA and the Federal Institute for Geosciences and Natural Resources (BGR) in Hannover, Germany, has now presented evidence for the theory of the meteorite impact. Scientists from the University of Münster were also involved in the study, which was published in the journal "Science". The discussion was based on various borehole samples - the most recent were taken during a deep-sea expedition of the Integrated Ocean Drilling Project in Newfoundland. These samples were examined in 2015 at the Institutes of Mineralogy and Planetology at Münster University for geochemical evidence of a meteorite impact. The scientists from Münster detected the so-called Iridium anomaly for the drill cores from Newfoundland, which was the first description for this locality This strong enrichment of the element iridium, which can be traced back to an asteroid impact 66 million years ago, confirmed by the discovery of the Chicxulub crater in Mexico in the early 1990s.
