While that bit may seem flippant, I also wonder about dinosaurs and scaling.
They don't seem to have half the supposed skeletal size that they 'should' according to simple scaling.
- Mz 17y agoMy understanding is that the earth's atmosphere used to be far denser and the oxygen concentration far higher. This is what allowed giant roaches and the like to exist at one time. Dinosaurs evolved in a different world than we live in. I'm not real up on this information -- it's my sons who are really interested in it, not me -- but this detail sticks with me because I used to really be bothered by giant spiders in movies. One day, while watching something on TV that talked about dinosaurs and other historical critters, they showed a very large spider and said "If this spider were alive today...(it would the size of a house cat or hunting house cats or something)" and I said "If it were alive today, it would be on life support." My sons cracked up. And I no longer get freaked by giant movie spiders. They can't exist in earth's current atmosphere, which is why they don't exist on earth today.
