Latest K–T boundary Stories
Researchers claim to have uncovered new evidence supporting the notion that a Manhattan-sized asteroid collided with the Earth some 66 million years ago, triggering a global firestorm that would have led to the extinction of 80 percent of the planet’s species.
Disregard of three critical protocols explains why a group challenging the theory of a North American meteor-impact event approximately 12,900 years ago failed to find iron and silica rich magnetic particles in the sites they investigated.
A cosmic one-two punch of colossal volcanic eruptions and meteorite strikes likely caused the mass-extinction event at the end of the Cretaceous period that is famous for killing the dinosaurs 65 million years ago.
University of Colorado researchers have found that worms were among the first animals to surface after an asteroid plowed into the Gulf of Mexico 65.5 million years ago.
The debate whether dinosaurs went extinct due to a large space rock that struck the Earth over 65 million years ago may have been answered with the discovery of a distinctive brow horn from a Ceratopsian dinosaur just 13 centimeters below the K-T boundary.
For decades, scientists have accumulated ever-larger datasets that suggest an enormous space rock crashed into the ocean off the Yucatan Peninsula more than 65 million years ago, resulting in the Cretaceous-Paleogene (K-Pg) extinction.
A mysterious basin off the coast of India could be the largest, multi-ringed impact crater the world has ever seen. And if a new study is right, it may have been responsible for killing the dinosaurs off 65 million years ago.
A Princeton University geoscientist who has stirred controversy with her studies challenging a popular theory that an asteroid wiped out the dinosaurs has compiled powerful new evidence asserting her position.
The enduringly popular theory that the Chicxulub crater holds the clue to the demise of the dinosaurs, along with some 65 percent of all species 65 million years ago, is challenged in a new paper published Monday.
