They say there must have been a higher concentration of Oxygen in the air to support the bigger bodies -- especially large insects because they don't breath. Maybe they're wrong though.
Well, it's difficult to say if Oxygen had necesserily to play its role here. Contemporary phisiology already clearly proved every creature needs not too much Oxygen to sigh. Humans need something about 24% Oxygen in the air to get healthy long life. Other animals need Oxygen almost such concentration... Of cause, climate do change, atmosphere changes. There is no anything not changing here at all! But if we say phisical laws are steady we must proceed meaning that till the very end. In Russia, we say: "If you've said 'A', then say and 'B'". Phisical laws don't change in time, do they? So, there took place a number of experiments in Antarctica. If I remember correctly, it was Russian phisician Kapitsa who presented those experiments at an International Meeting of scientists. He asserted that consistention of atmosphere did not very much change last several thousands of years. And obviously "they're wrong though
", as you said.
And who a hell had said insects do not breath. I'd advise to catch a fly and close it in a glass tin. How long will it stay alive that "unbreathing" poor fly?!
I don't know about the turtle. Perhaps it just moved very slowly so as not to faint.
Why slowly? That turtle must've had rather long members of body to move slowly. I just had a turtle at home six years ago. If it lies under the sunshine enough, it can run faster, than several our modern scientists can think!
I don't know about the turtle, too.
Perhaps the dino's had some super gas & temperature exchange abilities, or maybe an oil-cooled dino heavy towing package.
Oh, I know it's not your own opinion, but please don't tell me about "super gases
". Do the scientists really
say it seriously!? I don't believe it! Although the "package
" looks like truth. But in this case we must have agreed evolution takes much more time than it usually is thought. Revolutionary transformations in phisiology of creatures takes too much time. And we know animals of past are to be relatives to those of future, they're progenitors. And how could that 60 mln. years is fit to such magical changings! But if I'm not mistaken the carbon analysis don't let time to be rubber, does it?
Another possibility is that they cut down on their need for oxygen by holding their breath and simultaneously cooling themselves with the gas expansion of continuous methane backfirings
"Another possibility is
" just one more phantastical theory... Animals would acclimatise any atmosphere ever be
! Even Ch. Darwin repeated that till death. He called it adaptability of species. And methane's just a news for world of developed creatures.
They show pictures of what they say is a hammer encrusted with stone, but that the metal could not be smelted in our current atmosphere...I want to say it was something about chlorine content within the metal.
Yes, and animals could live on and on even in acid atmosphere. I'm not sure if it's connected with their height and mass. Even today there live enormous animals, both mammalia and reptyles. Look at elephants, crocodyles, cetus and so on! Is our air rich with "chlorine
"? It isn't. That hammer was just accidentally chlorined, it seems.
One thing I remember is that they said the sky would be a reddish-pinkish-orangish instead of blue because of the chemical composition.
I heard of it. Buddhist lamas assert on the fact of another colour of the sky in deep past. But if I didn't forget they ground this on their theory. It says Earth Poles go up and down from time to time. And earlier the North Pole was situated in Himalayas, and in future it'll change its position. I have no time to describe the Poles' teaching but I must confess it's much closer connected with logic that all the hypoteses to be meantioned above. And modern science partially agreed Poles change. Our scientists have very many things to hammer away at. They'll never be unemployed I guess.
