Study Settles Debate Over What Wiped Out the Dinosaurs?

A new study looking at the demise of the dinosaurs may have settled the debate over what caused the mass extinction event millions of years ago. The puzzling mystery has long perplexed scientists and, over the years, two competing camps have emerged. One school of thought suggested that an asteroid strike was responsible for wiping out the iconic creatures, while another hypothesis argued that volcanic activity was to blame. Meanwhile, some pragmatic observers went so far as to propose that perhaps the two events worked in tandem to create the circumstances necessary for such an Earth-shattering event.

The answer to the vexing question may finally have been determined thanks to research which reportedly looked at complex ecological models simulating conditions on the planet following either an asteroid strike or "massive volcanism" as well as both events simultaneously. The study found that the only scenario which could account for such widespread extinction is an asteroid strike as it would have left nearly the entire planet uninhabitable for dinosaurs by way of an "impact winter" lasting for decades, while "effects of the intense volcanic eruptions were not strong enough to substantially disrupt global ecosystems."
