After years of detective work, University geosciences professor Gerta Keller and her colleagues have found that an intensive period of volcanic eruptions and a series of asteroid impacts likely ended ...
Massive volcanic eruptions did not cause the extinction of dinosaurs, according to a new study. Volcanoes on the Indian peninsula have long been proposed as an alternative cause for the demise of the ...
The end of the dinosaurs was not just a spectacular finish, it was a brutal reset of life on Earth. In the geological instant ...
The 5.3-mile-wide crater is now confirmed to be 66 million years old, suggesting that the impact of at least two giant space rocks preceded the mass extinction of dinosaurs. Reading time 3 minutes ...
The researchers are not the first to propose that the space rock belonged to a group of asteroids that formed beyond the orbit of Jupiter. Their findings, however, strengthen the case thanks to a rare ...
A recent study led by geosciences professor Gerta Keller challenges the most commonly-held belief for the mass-extinction of dinosaurs at the end of the Cretaceous period 65 million years ago. The ...
