Dinosaurs: Two Asteroids Marked the Disappearance

Not a single asteroid, it turned out that there were two asteroids that hit the Earth about 65 million years ago. This marked the end of thewere gods dinosaurs. This cemented the transition from the Cretaceous to the Paleogene. The universities of Texas, Arizona and Edinburgh participated in the study. It has become a new one crater called Nadir, after the name of a nearby seamount of volcanic origin. It lies at the bottom of the Atlantic Ocean, off the coast of Guinea, 8.5 kilometers wide and several hundred meters deep.

The discovery happened by chance. They dated the crater around theit was geological of the Chicxulub asteroid. The dating took place thanks to an ultrasound of the geological layers sending pressure waves over the ocean and the seabed. Then detect the reflected energy. Here’s that the similarity in age between the two asteroids has given rise to the hypothesis that the two could have fallen to Earth at the same time.

The famous asteroid of Chicxulub is located in Yucatan, Mexico. The impact dates from 65.95 million years ago with a diameter between 10 and 14 kilometers. It released a more powerful energy than the Tsar’s bomb. The Nadir asteroid is smaller than the Chicxulub asteroid and may have contributed to the most dramatic event in Earth’s history. This is thebecome extinct of the Cretaceous mass. Then the unbelievable reduction in the number living species leading to the disappearance of 80% of marine and continental species, including dinosaurs.

The study has already requested permission to take samples from the crater to determine the age and presence of minerals formed in the impact. This is the only way we can determine whether the body that caused the collision is a piece separate from the Chicxulub asteroid. Or from other pieces of asteroids from the same period.
