A record of volcanism preserved along ancient mid-ocean ridges provides evidence for heightened worldwide magmatic activity 66 million years ago just after the Chicxulub meteor struck Earth, according to University of Oregon ...
Researchers at the University of Birmingham have discovered that the mass extinction seen in plant species caused by the onset of a drier climate 307 million years ago led to extinctions of some groups of tetrapods, the first ...
Scientists from the University of Bristol have revealed that ray-finned fishes are perhaps one of Earth's most resilient groups of animals, having survived four mass extinction events that wiped out many other groups.
One of the key effects of the end-Permian mass extinction, 252 million years ago, was rapid heating of tropical waters and atmospheres.
Sixty-five million years ago, clouds of ash choked the skies over Earth. Dinosaurs, along with about half of all the species on Earth, staggered and died.
Black rhinos, red wolves, whooping cranes: the global list of endangered species grows every year to the point where some researchers say we're witnessing the start of Earth's next mass extinction.
During Antarctica's summer, from late November through January, UW-Milwaukee geologists Erik Gulbranson and John Isbell climbed the McIntyre Promontory's frozen slopes in the Transantarctic Mountains. High above the ice fields, ...
One of the largest global mass extinctions did not fundamentally change marine ecosystems, scientists have found.
Millions of years ago, a mountain range that would have dwarfed the Andes mountains in South America, stretched over what is currently the southern-most tip of Africa.
Mass extinctions were followed by periods of low diversity in which certain new species dominated wide regions of the supercontinent Pangaea, reports a new study.
