Dinosaur extinction was caused by an asteroid impact 66 million years ago that also triggered a series of volcanic eruptions, say researchers from the University of California Berkeley.
The earliest North American coral species that reappeared following the Triassic-Jurassic mass extinction were found at New York Canyon in Nevada. This sheds light on the corals' survival and recovery.
No, it isn't the End of Days, but we are likely living during what experts will later refer to as one of the largest extinction events in Earth's history - an unexpected addition to prehistory's "Big Five" mass extinctions.
Sixty-six million years ago, a massive asteroid struck Mexico's Yucatán Peninsula. As a result, the Earth changed forever, spelling the end of the dinosaurs and ushering in a new age where other animals could flourish. Now new research has revealed that it wasn't mammals who inherited the Earth, but fish.
New statistical analysis has provided a very precise record of climate change in the Pleistocene, including its effect on mammoths, say researchers.
As far as scientists know, there have been a grand total of five mass extinctions over the last 500-million years - world-changing events during which the great majority of Earth's life was eliminated to make way for new organisms and evolutionary paths. However, for several decades, some experts have suspected that a 6th mass extinction existed among these "Big Five." Now researchers are claiming to have found extremely compelling proof of its existence.
It's no secret that ocean acidification caused by climate change is currently wreaking havoc on our oceans, but a new study shows that acidic oceans also triggered the greatest mass extinction ever on Earth.
It turns out that toxic oceans are to blame, at least in part, for an ancient mass extinction event that occurred over 200 million years ago, new research says.
It is thought that about 66 million years ago, a massive impact led to the full extinction of the dinosaurs (potentially with the help of volcanoes and disease), and a significant portion of prehistoric sea life. Now researchers have found evidence that even the great majority of mammals at this time did not escape destruction.
New fossil evidence is pointing to the possibility of a sixth mass extinction event in Earth's past, and this one may have helped usher in the largest "great dying" that that ever occurred. If that is right, the Permian period may have actually been hit with a two-punch knockout that caused more species loss than the infamous extinction of the dinosaurs.
Incredibility small diamonds laced through an unassuming layer of earth may be a major clue in telling just what happened to some of North America's largest mammals 13,000 years ago.
Earth appears to be in the early stages of the planet's sixth mass biological extinction event, according to a new study, with a 25 percent decline in populations of what species are still left.
