Mammals began to flourish well before the end of the dinosaur age, a new study has found. The study saw hundreds of mammal fossil teeth analysed by the Universities of Southampton and Chicago. The findings showed those with varied diets began to adapt 10 to 20 million years before the dinosaurs died out.
Researchers said it contradicted the traditional view that the extinction of dinosaurs around 66 million years ago allowed mammals to evolve and thrive. Source: BBC News
