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. 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. The devastation wrought by the impact almost certainly explains the sudden death of the land-based dinosaurs, according to fresh analysis of the latest data. But one scientist on the team said the beasts might have prevailed had the asteroid struck earlier or later than it did. The scientists' report, published in Biological Reviews, found that while, largely, the dinosaurs were faring well at the time of the asteroid impact, the big plant-eating types, had suffered a loss of biodiversity. The loss of biodiversity in plant-eating dinosaurs left fewer animals at the bottom of the food chain for larger beasts to prey on. less
