The extinction of the dinosaurs has puzzled scientists, who attributed it to the collision of a fiery meteorite with the Earth some 66 million years ago, followed by the eruption of volcanoes and the burning of forests on our planet. But a new study suggests that the dinosaurs were already endangered millions of years ago, before the alleged meteor hit Earth, according to an analysis of more than 1,000 pieces of this animal’s fossilized eggshell discovered in central China. Study author Qiang Wang of the Chinese Academy of Sciences said, “Dinosaurs gradually became extinct over millions of years and did not suddenly end up due to disasters.”
The study, conducted by a team of geologists and paleontologists working in China, shows that dinosaur biodiversity began to vanish at least two million years before their general extinction; At the end of the Cretaceous he left the birds, including their only living descendants.
