The "fact" about Dinosaurs and oxygen is BS.
Mammals needs more oxygen than reptiles and birds. The oxygen level have increased since Jurassic times.

However, during the Carboniferous period, there was much more oxygen that today which allowed for giant insects to exist.
Never underestimate the power of large crowds, of stupid people.
