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, […]

The discovery unearthed in Uzbekistan provides key insights into how a family of small-bodied dinosaurs evolved over millions of years to become fearsome giants. The study shows that the dinosaurs — known as […]
During Patrick Druckenmiller’s not-so-restful sabbatical year, he is flying to museums around the world. In Alberta a few weeks ago and London now, the University of Alaska Museum’s curator of earth science is looking at bones of dinosaurs similar to ones found in northern Alaska. The more he squints at them and chats with experts, […]
