In the wiki article you reference on Pterosaurs where do you get the interpretation that
quote:
with existing air pressure they would not be able to fly in our day.
The wiki article that you reference states “Pterosaur wings were formed by membranes of skin and other tissues”, “much the same as modern bats and flying squirrels”. So where you get this difference in atmospheric pressure from just 4500 years ago is kinda puzzling, especially since your own reference states that the Pterosaurs had hollow bones filled with air, much the same as modern birds . did you even bother to read your source before posting it?
