恐竜は約6500万年前に惑星から姿を消した。彼らの絶滅の特定の理由は科学的議論の対象のままですが、最も一般的に受け入れられている説明は、大規模な小惑星の衝撃が広範囲にわたる火と「核冬」に似た冷却効果をもたらしたということです。これにより、恐竜や他の多くの種にとって生存が困難になりました。
The dinosaurs disappeared from the planet approximately 65 million years ago. While the specific reason for their extinction remains a subject of scientific discussion, the most commonly accepted explanation is that a massive asteroid impact resulted in widespread fires and a cooling effect akin to a "nuclear winter", caused by blocking out the sun. This made survival challenging for dinosaurs, as well as many other species.
