KONTAN.CO.ID – Revealed! This is when the asteroid hit Earth which made the dinosaurs extinct. An asteroid called Chicxulub that ended the life of the dinosaurs apparently fell in the spring of 66 million years ago.
Dinosaurs are still a mystery to this day. In fact, the extinction of T-Rex and his friends has not yet been fully revealed by scientists.
Over time, finally the mystery of the extinction of the dinosaurs was revealed. Including, when the asteroid hit the Earth that made the ancient animal not left.
Quoted from Sciencealertabout 76% of dinosaur species disappeared as they struggled to cope with climate change after the asteroid Chicxulub hit Earth about 66 million years ago.
The only surviving dinosaurs are bird species that may have been lucky when the asteroid hit Earth’s surface.
Quote from The Sunin addition to bird species, some mammals, crocodiles, and turtles also managed to survive.
The event that made dinosaurs extinct was more precisely in the spring of 66 million years ago. This became a buzzword because it would be the start of the breeding season in the Northern Hemisphere, where it was spring but the asteroid suddenly stopped them all.

Meanwhile, it’s autumn in the Southern Hemisphere, where others are gearing up for winter to hibernate.
“We found bones that record seasonal growth, very much like trees, growing a new layer every year on the outside of the bone,” said Sophie Sanches, a researcher from Uppsala University.
“The extracted growth rings not only capture the life history of the fish but also record the most recent Cretaceous season, and thus the season in which the catastrophic extinction occurred,” added Jeroen van der Lubbe, senior author at VU in Amsterdam.

The researchers used the remains of sturgeon fish and filter paddle fish to determine the timing of the asteroid strike. They looked closely at the growth patterns preserved in the fossil bones.
This is what can indicate the seasons in a similar way to the rings on the trunk of a tree. Research entitled The Mesozoic terminated in boreal spring This was published February 23, 2022 in the journal Nature.
