Did the extinction of the dinosaurs begin even before the asteroid collided?


Mexico, December 6, 2021, Monday

Scientists have long debated how the giant dinosaurs that roamed the earth millions of years ago became extinct. The most well-known theory for the extinction of dinosaurs is that asteroids or meteorites collide with Earth. The Chicksulab meteorite collided around the Yucatan Peninsula in Mexico 25 million years ago, triggering the cataclysmic palaeogen extinction.


According to another theory, dinosaurs could not survive the beginning of the ice age due to climate change. According to recent claims, the extinction of dinosaurs began 10 million years before the asteroid collided with Earth. According to a study published in the journal Nature, figures and findings from 1,200 dinosaur fossils found around the world were looked at. Based on this, researchers have developed a model. In the North Cretaceous, carnivorous and herbivorous dinosaur species were found roaming. Fabian Kodamine, a researcher at the Matpillars Institute of Revolutionary Sciences and lead author of the new study, said there was a special focus on the process of reducing the number of dinosaurs. There were more than 50 species of dinosaurs, with their population at an all-time high of 25 million years ago. Since then, the number of dinosaurs has been declining for 10 million years.


The dinosaurs were accustomed to a mesothermal environment that kept them warm and humid. Gradually the weather began to decline with the onset of cold. With the onset of cold weather, the average temperature reached 4 degrees. Giant creatures, including dinosaurs, have not been able to adapt to the growing cold. At first the vegetarian and then the carnivorous species began to dwindle. The period between the two was 3 million years. In the midst of all this, some species of dinosaurs survived, but were wiped out by meteorite collisions. The decline of dinosaurs began 10 million years ago. About 40 species of dinosaurs were found.
