K/T asteroid impact. Computer artwork,centred on the Yucatan Peninsula,where a massive asteroid impact (yellow) is thought to have brought about the extinction of the dinosaurs. This event,some 65 million years ago,marks the boundary between the cretaceous and tertiary eras,and is know as the K/T boundary. North is at top. Land is green and water is blue. Landforms are seen as they were at the time. Scientists believe that the asteroid that hit Earth was up to 20 kilometres in diameter,and that the impact created six months of total darkness and decades of low global temperatures | |
