Ancient Yucatán: Asteroid Impact and Dawn of Mammals – AI Generated Video | Hailuo AI

Generate & Play Hailuo AI video：About 66 million years ago, at the end of the Cretaceous period, non-avian dinosaurs (i.e., all but birds) disappeared in a mass extinction. The main cause was most likely the impact of an asteroid (approximately 10 km in diameter) in the Yucatán region of Mexico, creating the Chicxulub crater. Consequences of the impact: - Megatsunamis, massive fires, and dust clouds blocking sunlight. - Abrupt climatic cooling ("impact winter"), disrupting photosynthesis and food chains. - Ocean acidification and ecosystem collapse. Other factors, such as massive volcanic eruptions in the Deccan Traps (in India), may also have contributed to weakening species before the impact. **Result:** - **Disappearance of 75% of species**, including non-avian dinosaurs, pterosaurs, and large marine reptiles. - **Mammals and birds** survived and were able to diversify, leading to the Age of Mammals (including the evolution of humans, much later). Avian dinosaurs (ancestors of modern birds) are the only ones to have survived to this day. **In short:** An asteroid + environmental disasters = the end of the dinosaurs (but not all of them!).
