Dunno if that is all correct but at the time when I read the article it seemed like a good plausible story to me.
'...At a meeting of the Geological Society of America held last Fall in Phoenix, Robert Brenner of Yale
University and Gary Landis of the U. S. Geological Survey reported the results of a QMS analysis of
ancient air bubbles trapped in amber.
They obtained a remarkable result. The atmosphere of the Earth 80 million years ago was discovered to
have 50% more oxygen than modern air. Brenner and Landis found that for all gas samples taken from
amber 80 million years old the oxygen content ranged between 25% to 35% and averaged about 30%
oxygen. Cretaceous air was supercharged with oxygen...'
