我们发现,在动物寿命谱中,恐龙的爬行类亲戚(主要是龟)寿命之长超过了大多数动物。而与恐龙一脉相承的一些鸟类,也在高寿之列。一些古生物学家对恐龙骨骼的生长环进行研究,他们发现,这些恐龙死亡时的年龄为120岁。没有证据表明它们是在年长之后自己慢慢老死的。许多恐龙死于事故。因此120岁并不是恐龙真正的寿命。 We found that in the animal lifespan spectrum, dinosaur reptilian relatives (mainly turtles) live longer than most animals. And the same strain of dinosaurs and some birds, but also the list of longevity. Some paleontologists studied the growth rings of dinosaur bones and found that the dinosaurs died at the age of 120. There is no evidence that they are aging slowly after they are old. Many dinosaurs died of accidents. Therefore, 120-year-old dinosaur is not the real life expectancy.
