| Video Discription | š Today, many extinct animals are more familiar to us than some species that are still alive. Among them are the dinosaurs. The diplodocus is more famous than the aardvark, and the tyrannosaurus more famous than the peramete. 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 was confronted with 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 enabled the evolution of mammals and birds, which are now highly diversified groups of animals. Without this extinction, dinosaurs would probably 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, redistributing the cards by condemning certain groups and giving new opportunities to others. When the dinosaurs disappeared, our distant ancestors survived. What did the Earth look like after the extinction of the dinosaurs? š„ As a reminder, videos are published on SUNDAYS at 6pm. ------------------------- š„ How did life on Earth recover after the cataclysm that brought down 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. Over the last 500 million years, life on the planet has undergone 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 deadly. Each of the great mass extinctions has played a role in the history of the living world, forcing it into new directions as decimated fauna and flora are forced to evolve. The Ordovician-Silurian extinction took place 444 million years ago. A geological event triggered an episode of glaciation. Considerable quantities of water became trapped in an ice cap 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. Probably due to a strong volcanic episode, 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 ever experienced by life on Earth. Over 90% of all species were killed. The destroyed forests will need more than 10 million years to recover. Around 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 was a further 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. ------------------------- š¬ Today's program: - 00:00 - Introduction - 02:35 - The phenomenon of mass extinctions - 08:30 - The face of the Earth at the time of the dinosaurs - 09:27 - Marine life at the time of the dinosaurs - 14:30 - Life on land in the age of the dinosaurs - 24:12 - 5th mass extinction marks end of dinosaur world - 33:03 - Assessment of the catastrophe on flora and fauna - 36:34 - The beginning of a new world: What was the world like after the dinosaurs went extinct? - 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 carnivorous climbers - 55:26 - Large amphibious herbivores - 55:56 - Cetaceans - 58:22 - Bats and Dermoptera - 59:31 - Vegetation after the extinction of the dinosaurs - 01:01:40 - The emergence of birds, heirs to the dinosaurs - 01:07:00 - Geological transformations of the Earth - 01:09:43 - The new giants Wondody is an official channel affiliated to the network Ā©ORBINEA STUDIO |
