恐龙灭绝的时间是在距今6500万年前。而且在那个时候，不仅统治了地球达一亿多年的各种恐龙全部绝灭了，同样悲惨的命运还同时降临到了地球上的陆地、海洋和天空中生活的很多种其它的生物。

还有一部分幸免于难的恐龙（大多体形较小）以及一些早在侏罗纪就已经进化为原始鸟类、哺乳类的动物、遵循自然界物竞天择、适者生存的法则，在相对恶劣的环境中，经过7000万年不断演变，大多数物种改变了原来的形态，由冷血动物进化为耐寒的能调节体温的热血动物（鸟类、哺乳类及人类）。当然，每次大规模物种进化后，总会有一些物种保留原状，像鱼类进化为两栖类后，鱼类还延续生存，爬行类中也有极少数（鳄、蜴蝎等）至今仍然保持了7000万年前恐龙的原始形态。

另外还有「传染病」、「来自宇宙的放射线或超新星的爆炸」「未乘上诺亚方舟」、「太阳系震动说」等。
