When the asteroid struck our planet some 66 mil years ago, it created a 180-km impact crater and produced a gigantic magma chamber. A new research found that this hydrothermal system supported an entire microbial ecosystem.
100 million years ago, ferocious predators, including flying reptiles and crocodile-like hunters, made the Sahara the most dangerous place on Earth.
Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
Called the "frozen dragon of the north," a new species of flying dinosaur, Cryodrakon boreas, has been discovered in Canada. The pterosaur is thought to have had the wingspan of a small airplane.
