Cretaceous-Tertiary extinction event. Image 8 of 8. Artwork of a mammal facing a new dawn after the asteroid impact that caused the extinction of the dinosaurs. The asteroid impact took place around 65 million years ago, marking the end of the Cretaceous period and the beginning of the Tertiary period. The impact took place at sea, and water vapour and molten rock (from the seabed) was thrown up into the atmosphere, causing forest fires. Dust thrown into the atmosphere lowered global temperatures. Plant and then animal life began to die off. The dinosaurs never recovered, and mammals rose to become the dominant form of life. For the sequence, see images E402/173 to E402/180.
