Latest Cretaceous–Tertiary extinction event Stories
After the asteroid impact at the end of the Cretaceous period that triggered the dinosaurs' extinction and ushered in the Paleocene, leaf-mining insects in the western United States completely disappeared.
Forests affected by fires 66 million years ago during the last days of the dinosaurs recovered no differently than they do today, according to a team of researchers from McGill University and the Royal Saskatchewan Museum.
According to Jason Moore from Dartmouth College, who presented a study at the 44th Lunar and Planetary Science Conference, evidence from the Chicxulub crater suggests there are possibilities beyond an asteroid impact.
Popular theory suggests that a massive asteroid smashed into Earth around 65 million years ago wiping most life, including the dinosaurs, off the face of the earth. But scientists have found evidence of another planetary cataclysm that occurred some 135 million years before the Cretaceous-Paleogene Extinction (CPE) event.
Scientists have winnowed the precision of the dates regarding the extinction of the dinosaur and the well-known impact that occurred around the same time.
Despite the name, a new species of lizard reported about in the scientific journal Proceedings of the National Academy of Sciences is not related to our President, because it went extinct when the giant asteroid hit Earth millions of years ago.
Paleontologists have been riddled by the fossil of a creature they dubbed Necrolestes Patagonensis, or Grave Robber. Now, another, much older fossil has been found, and paleontologists believe this creature was somehow able to survive the mass extinction event which killed the dinosaurs over 65 million years ago.
A mass extinction, wiping out numerous species including the dinosaurs, marked the end of the Cretaceous Period. A new study reveals that the structure of North American ecosystems made the extinction worse than it might have been.
Sixty-five million years ago, the most studied mass extinction in Earth's history happened and the dinosaurs were wiped off the planet, but a new study indicates that a separate extinction came shortly before that.
An asteroid impact may have ended the reign of the dinosaurs here on Earth about 65 million years ago, but new evidence suggests many of the large, plant-eating dinosaurs were already dying out during the last 12 million years of the Cretaceous period.
