Dinosaurs might have survived the catastrophic impact that ended their reign had the devastating asteroid that slammed into the Earth arrived at a "more convenient time", a scientist has claimed. As a result humans would probably not exist, according to The Guardian.
The violent collision 66m years ago, which occurred in the area that is now Mexico, triggered tsunamis across the oceans, caused powerful earthquakes and released enough heat to start many fires.
Material thrown into the air descended as acid rain, and also blocked the sun's warmth, cooling the Earth temporarily, perhaps by tens of degrees celsius. A thick blanket of dust that was thrown up darkened the globe, affecting plants and other photosynthesising life, The Guardian reports.
