Dinosaurs died because of an asteroid impact

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". ...
