L'era dimenticata: Cosa accadde veramente DOPO l'estinzione dei dinosauri? | Documentario Terra

🌍 Today, many extinct animals are more familiar to us than some living species. Among them are dinosaurs. The diplodocus is more famous than the aardvark, and the tyrannosaurus rex more so than the peramthes. Dinosaurs are part of popular culture. For over 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 its subsequent 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 today are highly diverse groups of animals. Without this extinction, dinosaurs would likely have continued to dominate life on Earth, and other animals would not have had the opportunity to make their mark. Mass extinctions change the rules of the game, reshuffling the deck, dooming some groups and creating new opportunities for others. When the dinosaurs disappeared, our distant ancestors survived. What did the Earth look like after the dinosaur extinction? 🔥 As a reminder, videos are posted on SUNDAYS at 6:00 PM. ------------------------- 💥 How did life on Earth recover after the cataclysm that took down the giant dinosaurs? A mass extinction is an event resembling a relatively brief biological crisis on the geological timescale. 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 experienced five mass extinctions. Today, over 99% of all organisms that have ever lived on Earth have disappeared. The phenomenon of species extinction is no longer surprising. Species are mortal. Each of the great mass extinctions has played a role in the history of the living world, pushing it in new directions as decimated fauna and flora are forced to evolve. The Ordovician-Silurian extinction occurred 444 million years ago. A geological event triggered an episode of glaciation. Significant quantities of water were trapped in an ice sheet three times the size of present-day Antarctica. This event led to the disappearance of 85% of all terrestrial species. The Devonian extinction began 383 million years ago. Likely due to a powerful volcanic event, 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, occurred 252 million years ago. It was the worst catastrophe ever experienced by life on Earth. Over 90% of all species were wiped out. The destroyed forests will take over 10 million years to recover. About 200 million years ago, the Earth suffered the Triassic-Jurassic extinction event. These geological events caused the Earth's surface to warm and the concentration of carbon dioxide in the atmosphere to rise. This was a further blow to life on Earth, which lost up to 80% of 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. ------------------------- 🎬 Today's Schedule: 12:00 AM - Introduction 2:35 AM - The Phenomenon of Mass Extinctions 8:30 AM - The Face of the Earth in the Time of the Dinosaurs 9:27 AM - Marine Life in the Time of the Dinosaurs 2:30 PM - Life on Land in the Time of the Dinosaurs 12:12 AM - The Fifth Mass Extinction Marks the End of the Dinosaur World 12:03 PM - Assessment of the Catastrophe on Flora and Fauna 12:34 PM - The Beginning of a New World: What Was the World Like After the Extinction of the Dinosaurs? 38:50 - The Last Giant Birds 41:00 - Hoofed Animals 44:48 - Large Herbivorous Ungulates 45:53 - Large Carnivores 47:10 - Primates 53:58 - Small Climbing Carnivores 55:26 - Large Amphibian Herbivores 55:56 - Cetaceans 58:22 - Bats and Dermopterans 59:31 - Vegetation after the Extinction of the Dinosaurs 01:01:40 - The Appearance of Birds, Heirs of the Dinosaurs 01:07:00 - The Earth's Geological Transformations 01:09:43 - The New Giants This channel is an official affiliate of the ORBINEA STUDIO network.
