Dinosaurs became extinct due to climate change | According to Nature

The Meteor impact 65 million years agoin the present-day Mexican region of Yucatan, Caused a series of disasters that led to The dramatic climate change that wiped him out dinosaursAccording to the research published Wednesday in the journal nature.

A team of scientists led by Melanie Fein, of the Free University of Amsterdam’s Faculty of Science (Netherlands), and Dennis Vojten, of Uppsala University (Sweden), has produced a chronology of this extinction, the fifth that the planet has experienced.

The specialists explained that “The exact year in which this natural phenomenon occurred will never be known.”

The shock wave from the Chicxulub Crater traveled nearly 3,000 km and raised huge waves in the Western Inland Sea.which at that time crossed present-day America, from north to south.

As the water destroyed everything in its path, A rain of glazed sand fell from the sky, due to the immense heat of the collision in Yucatan.

The Tanis Archaeological Site, in North Dakota (US), is key because there are fossil remains of many animals that were swept away by some kind of tidal wave, according to the study.

Using high-resolution X-ray tomography at the European Synchrotron Radiation Laboratory (ESRF) in Grenoble, the scientists analyzed the fossils of three sturgeon and three paddle fish from tanis, and the first thing they realized was that the fish had actually died during the tides. wave

The report states that the fish “were alive and feeding when the collision occurred, in the last minutes of the Cretaceous.” They died within “15 to 30 minutes” after the meteor impact, according to During.

Analyzes carried out in the European laboratory showed that the fish had ingested the sand without actually digesting it.

Terrible fires broke out and a long “nuclear” winter fell on the surface of the earth.

The sky darkened and the plants died, causing the herbivores to die out. Among them are sauropods and, accordingly, their predators, tyrannosaurs, while acidifying the oceans.

TheThe consequences of the meteor impact in Chicxulub, equivalent to the explosion of tens of billions of atomic bombs such as those in Hiroshima, Lasted for thousands of years, all over the planet.
