The first and last animal-founded country on Earth, which lasted more than 200 million years, according to research and studies conducted by a number of scientists of the last century, summed it up that the sprawling “Dinosaur Country” fell with a fatal blow delivered by an asteroid from space in 66 million BC. And it hit the northern coast of the Yucatán state in Mexico overlooking its famous Gulf, and from there, in the last spring of its history, the era of the dinosaurs ended.
None of the scientists discovered that the most dangerous thing that attacked the Earth hit it in the spring in particular, only after a scientific team recently hired a fish, a team of scientists from Vrije University in the Dutch capital Amsterdam, and their peers at a university of the same name in the Belgian capital, Brussels. It also included scientists from Uppsala University in Uppsala, Sweden, and others at the European Synchrotron Radiation Facility for Synchrotron Radiation in Grenoble, southern France.
The team published its study in the prestigious scientific journal Nature, in which it stated that it reached its conclusions from finding in the US state of “North Dakota” the fossilized fossils of a fish known by the name “sturgeon” or Latin Acipenseridae, and the name of each of them is Sturgeon in English, and they were found after using x-rays Intense, and a review of the carbon isotope changes on their spines and fossilized bones, that millions of them died about an hour after the asteroid collision, whose force caused the generation of huge waves that moved the sediments and swallowed the fish and buried them alive.
Death surprised her in the spring
The team found that the fossils of these fish were originally preserved, and their senses did not show any signs of chemical change, according to what “Al Arabiya.net” summarized what I read about the study in which it was stated that the tissues of the mollusk fish remained intact. The team also looked at how her senses and bones developed “to find out the season in which she died,” according to Melanie During, a Dutch scientist from Uppsala University in Sweden, who is the lead author of the study.
In the study also, the carbon isotope data on the growth of the “sturgeon” fish confirm that the feeding season had not reached its peak at the time of the asteroid impact “because death surprised it in the spring.” While it was clear from the analysis of the fish through carbon isotopes to reveal its annual feeding pattern, that the availability of plankton Animals, which are what you like to eat, were at their peak between spring and summer.
From thistles and bones, scientists have come to the season that marked the beginning of the extinction of the dinosaurs
The scientist “Melani” also said that the findings of the team members “will help reveal the cause of the death of most dinosaurs, while birds and early mammals managed to escape extinction,” which is what Al-Arabiya.net also found in other studies available “online.” And remember that some types of crocodiles, turtles, rodents, insects and vermin were also able to survive, although the asteroid killed most of what was blowing, moving and floating, and blocking sunlight for more than two years, from the smoke of fires that ate the green and the land and unbearable ice prevailed.
