A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth.
Dinosaurs diverged from their archosaur ancestors during the Middle to Late Triassic epochs, roughly 20 million years after the devastating Permian–Triassic extinction event wiped out an estimated 96% of all marine species and 70% of terrestrial vertebrate species approximately 252 million years ago.
Scientists may have finally found where the object that wiped out the dinosaurs came from.. The mass extinction event that occurred 66 million years ago – the most recent on Earth – came about ...
Between 23% and 34.1% of marine genera went extinct. [1] [2] Plankton diversity dropped suddenly, [23] but it was relatively mildly impacted at the Triassic-Jurassic boundary, although extinction rates among radiolarians rose significantly. [24] Ammonites were affected substantially by the Triassic-Jurassic extinction and were nearly wiped out ...
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
New research shows that ants have been farming fungi for 66 million years — thanks in part to the asteroid that fueled the demise of the dinosaurs.
