Published in the scientific journal Geology , scientists have found surprising fossils at the Chicxublub impact crater, where the dinosaur-killing asteroid crashed to Earth 65 million years ago. The area is believed to be completely devoid of life before the collision.
Among these ancient specimens are numerous relatives of bacteria. While the huge dinosaurs and 75% of the earth’s creatures died, mysteriously, this space impact caused the small, silent but extremely important life form in the Earth’s ecosystem, to explode. powerful explosion.

In addition to bacteria, many types of phytoplankton and fungi also come to reside in this “death zone” , which, according to the team, is most likely swept in by the tsunami and sown seeds. From this strange nest , the bacteriophage family revived stronger than before and then spread across the Earth.
Lead author Professor Kliti Grice of the School of Earth and Planetary Sciences, Curtin University (Australia) said that although the post-disaster environment is believed to be extremely harsh for all life forms, phytoplankton still remains. develop at a rapid pace. The growth of phytoplankton, together with a great change in the supply of nutrients for life on earth, the source of oxygen … created a strong recovery of microbial life.
Therefore, replacing the death of the “monsters” named dinosaurs from the end of the Triassic, through the Jurassic, to the Cretaceous, the era of small “monsters” began. : that is different from cyanobacteria, anaerobic forms of sulfuric acid bacteria, and countless other forms of microorganisms. No matter how small, microorganisms are an integral part of shaping the face of the earth today.
What happened on the day the death asteroid killed the dinosaurs , it’s a great mystery that over time the scientific world has been figuring out a little more each day. Another study published in 2009 showed that a tsunami more than 1,500m high was created by the asteroid and devastated the Earth. And perhaps it was also the tsunami that “seeded” the microorganisms that this study found. Another study also in 2019 estimated that the asteroid hit the earth with the force of 10 billion atomic bombs.
