"... We estimate that pO2
was continuously above 26% during the Carboniferous and
Permian periods, and that it declined abruptly around the time
of the Permian–Triassic mass extinction. During the Triassic
and Jurassic periods, pO2 fluctuated cyclically, with amplitudes
up to 10% and a frequency of 20–30 million years. Atmospheric
oxygen concentrations have declined steadily from the middle
of the Cretaceous period to present-day values of about 21%. ..."

not envision wildfires in peat-forming systems. The advent of Scanning Electron Microscopy and
studies on modern charcoals and fossil fusains demonstrated beyond doubt that wildfire residues
may be recognized in rocks dating back to at least 350 million years ..."
