???? Today, many extinct animals are more familiar to us than some species that are still alive. These include the dinosaurs. The diplodocus is more famous than the anteater, and the tyrannosaurus more than the peramelid. Dinosaurs are part of popular culture. For more than 160 million years, these majestic creatures dominated the Earth, occupying most ecological niches and leaving little room for other species. On five occasions, the Earth faced major upheavals that had a fundamental impact on the rest of its history. When they disappeared during the fifth mass extinction, the dinosaurs left an immeasurable void. But one man's misfortune is another man's gain, and this void allowed the evolution of mammals and birds, which are now highly diversified groups of animals. Without this extinction, dinosaurs would likely have continued to dominate life on Earth, and other animals would not have had the chance to leave their mark. Mass extinctions change the rules of the game and redistribute the cards, dooming certain groups and giving new opportunities to others. When the dinosaurs disappeared, our distant ancestors survived. What was the Earth like after the extinction of the dinosaurs? ????

How did life on Earth recover after the cataclysm that wiped out the gigantic dinosaurs? : A mass extinction is an event that resembles a relatively brief biological crisis on the scale of geological time. At least 75% of animal and plant species disappear from the face of the Earth. In the last 500 million years, life on the planet has suffered five mass extinctions. Today, more than 99% of all organisms that have ever lived on Earth have disappeared. The phenomenon of species extinction is no longer surprising. Species are deadly. Each of the major mass extinctions has played a role in the history of the living world, leading it down new paths, with decimated fauna and flora forced to evolve. The Ordovician-Silurian extinction took place 444 million years ago. A geological event triggered an episode of glaciation. Huge quantities of water were trapped in an ice sheet three times the size of present-day Antarctica. This event caused the disappearance of 85% of all terrestrial species. The Devonian extinction began 383 million years ago. Probably due to a strong volcanic episode, the pulses caused a sudden drop in oxygen levels in the oceans. 75% of species disappeared during this mass extinction. The third mass extinction, the Permian-Triassic, took place 252 million years ago. It was the worst catastrophe known to life on Earth. More than 90% of species died. The destroyed forests will need more than 10 million years to recover. About 200 million years ago, the Earth suffered the Triassic-Jurassic extinction. Geological events caused a warming of the Earth's surface and an increase in the concentration of carbon dioxide in the atmosphere. This dealt another blow to life on Earth, which lost up to 80% of its terrestrial and marine species. The fifth and final mass extinction was the Cretaceous-Paleogene extinction, which caused the disappearance of the famous non-avian dinosaurs. ------------------------- ????
