Asteroid dinosaur extinction

How an asteroid ended the age of the dinosaurs. Sixty-six million years ago, dinosaurs had the ultimate bad day. With a devastating asteroid impact, a reign that had lasted 180 million years was abruptly ended. Prof Paul Barrett, a dinosaur researcher at the Museum, explains what is thought to have happened the day the dinosaurs died Yes, an asteroid really did wipe out the dinosaurs, study finds. A large armored dinosaur species, Ankylosaurus magniventris, drinks from a watering hole while an asteroid crashes on the Yucatán. Today, the asteroid crater is buried under the Gulf of Mexico. Scientists now think a 12km-wide object struck Earth 66 million years ago. The crater it produced is about 200km wide and is buried. A giant meteor that struck the Yucatán Peninsula 66 million years ago is the leading explanation for the demise of the dinosaurs. Illustration by Mark Garlick, Science Photo Library/Alamy..

Short-term (aerosol cooling) volcanism still allows equatorial habitability. These results support the asteroid impact as the main driver of the non-avian dinosaur extinction. By contrast, induced warming from volcanism mitigated the most extreme effects of asteroid impact, potentially reducing the extinction severity The Cretaceous-Paleogene (K-Pg) extinction event (also known as the Cretaceous-Tertiary (K-T) extinction) was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago. With the exception of some ectothermic species such as sea turtles and crocodilians, no tetrapods weighing more than 25 kilograms (55 pounds) survived These apparently died out suddenly and simultaneously, and their extinction accords best with the asteroid theory. The fossil evidence of land dwellers, however, suggests a gradual rather than a sudden decline in dinosaurian diversity (and possibly abundance) In February 2021, scientists reported studies suggesting the impactor that led to the demise of the dinosaurs 66 million years ago was a fragment from a disrupted comet, rather than an asteroid which has long been the leading candidate among scientists. Chicxulub and mass extinction

One of the best-known mass extinction events in Earth's history was the Cretaceous-Paleogene (K-Pg) extinction event. Dinosaurs were among the species that perished. It is widely believed that a large comet or asteroid impacted Earth and caused the extinction Although the asteroid impact created mass destruction at the regional level, it was this global climate change that caused a mass extinction, killing off the dinosaurs along with most other life on the planet at the time. The real killer has got to be atmospheric, Gulick said

Known as Chicxulub (CHEEK-shuh-loob), it's the dinosaur killer. The asteroid impact that caused a massive global extinction event can be found on the coast of Mexico. Google Maps/UT Jackson School of Geosciences Scientists are assembling the most detailed timeline yet of the dino apocalypse The Chicxulub asteroid explosion marked the end of the Mesozoic era. The explosion is also known as the Cretaceous-Tertiary extinction event, which is the mass extinction of animal and plant species on a large scale over a very short geological period. Because of that event, Earth had to go through years to fix all the chaos that occurred in it

Asteroid that wiped out the dinosaurs hit at 'deadliest

They proposed that a comet or asteroid impact was responsible for both the iridium at the K-T boundary and the mass extinction. Jan Smit, Mark Richards and Walter Alvarez at the North Dakota site of dinosaur-killing meteor's first victims An asteroid impact 66 million years ago may have released trillions of pounds of partially burned fossil carbon into Earth's upper atmosphere as a cloud of black soot, significantly contributing to the ensuing global darkness and cooling that led to a mass extinction and wiped out the dinosaurs The asteroid models show a relatively quick onset of subfreezing temperatures that would have lasted 3-16 years, with temperature recovering only after 30 years. That would have accounted for the geologically instantaneous extinction of the dinosaurs Although the asteroid impact created mass destruction at the regional level, it was this global climate change that caused a mass extinction, killing off the dinosaurs along with most other life.
