Latest Deccan Traps Stories
When it comes to theories on why the dinosaurs went extinct, massive and widespread volcanic activity has always played second fiddle to the more dramatic theory of a large asteroid slamming into Earth.
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.
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.
Seeking to better understand the level of death and destruction that would result from a large meteorite striking the Earth, Princeton University researchers have developed a new model that can not only more accurately simulate the seismic fallout of such an impact, but also help reveal new information about the surface and interior of planets based on past collisions.
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 U.S. study suggests violent volcanic eruptions in India might have killed the dinosaurs 65 million years ago, not a meteor impact.
There's growing evidence that the dinosaurs and most their contemporaries were not wiped out by the famed Chicxulub meteor impact, but by multiple meteor impacts, massive volcanism in India, and climate changes.
Earth history has been punctuated by several mass extinctions rapidly wiping out nearly all life forms on our planet. What causes these catastrophic events?
New discoveries about the timing and speed of gigantic, 6500-foot (2-km) thick lava flows that poured out of the ground 65 million years ago could shift the blame for killing the dinos.
Scientists can recite a long list of the devastating environmental consequences of a large meteorite impact, but they cannot prove these effects have led to the simultaneous loss of life around the globe. How and why such a large variety of species died out at the same time are two of the greatest mysteries in paleontology.
- The relation of a son or daughter to a parent: the correlative of paternity.
- The establishment of a filial relation, specifically by adoption.
