如果恐龙生活在城市,我们能找到痕迹?

假设至少65年前,恐龙(或者,就此而言,另一个物种)会充分发达与房屋建立定居点,道路等。

考古学家们能够识别这些结构6500万年后?或将侵蚀,构造变化和消除任何可能的痕迹吗?我的想法是这样的:一个可以认为为由太小的大脑,恐龙没有“文明”,因此没有离开建筑物。但是,一个考古理由反对吗?

回答

“缺乏证据是不缺乏的证据。”That said, there is no evidence of any intelligent civilization prior to humanity. If dinosaurs, or for that matter, some other species, had achieved our current human level of civilization, only to be wiped out by an asteroid collision with the Earth, there would be evidence that that high level civilization had happened. We wouldn't see the huge deposits of coal and oil dating back to the Carboniferous and the huge deposits of iron dating back to the two billion year old oxygenating of the atmosphere, all of which we are currently exploiting. We would see strange bands of iron embedded in very thin and narrow but very long rock formations (i.e., 65 million year old freeways). We don't see any of that. A dinosaur equivalent of our current level civilization can be ruled out. On the other hand, if dinosaurs or some other species had only achieved the equivalent of pre-pottery Neolithic civilization when the first towns were being built by humans (about 10000 years ago), only to be wiped out by an asteroid collision with the Earth, there might well be no evidence of that. It has been hard enough for archeologists to find the rather faint signs of those 10000 year old civilizations, and that's mostly because those archeologists know where to look. Finding signs of an equivalent 65 million year old civilization where no one knows where to look would be nigh impossible. Lack of evidence is not evidence of lack.
