Dinosaur extinction,artwork. Trail of dead triceratops scattered on barren land. This illustration could represent the extinction of the dinosaurs. There are various theories regarding the cause of the extinction and most focus on a single catastrophic event such as a volcanic eruption or a meteorite impact which took place at the end of the Cretaceous period,65 million years ago. Both events can trigger a lowering of global temperatures as clouds of dust and ash reduce the amount of sunlight reaching the surface. Plant and then animal life dies off | |
