How the darkness and the cold killed the dinosaurs
2017-01-12 23:00:00| LifeSciencesWorld
[NEWS] 66 million years ago, the sudden extinction of the dinosaurs started the ascent of the mammals, ultimately resulting in humankind's reign on Earth. Climate scientists now reconstructed how tiny droplets of sulfuric acid formed high up in the air after the well-known impact of a large asteroid and blocking the sunlight for several years, had a profound influence on life on Earth. Plants died, and death spread through the food web. Previous theories focused on the shorter-lived …

Say dinosaur, and most people think of the great flesh-eaters such as Tyrannosaurus rex, but the most successful dinosaurs were of course the plant-eaters. A new study from the University of Bristol, led by Masters of Palaeobiology student Eddy Strickson, has presented clear evidence about how plant-eating dinosaurs evolved. In the rich dinosaur deposits of North America, hundreds of skeletons of…

Agence France-Presse: The dinosaurs` long reign was not ended by a merciful knockout punch, but by a torturous millennia of climate change before and after the oft-blamed space rock slammed into Earth, scientists said Tuesday. The impact at Chicxulub in modern-day Mexico certainly contributed to the disappearance of the giant lizards and other creatures, but was by no means the sole cause, a team concluded in a study published in Nature Communications. Of 24 mollusk species which went extinct at one Atlantic island,...
