"Over 300 million years ago, before the age of giant dinosaurs, Earth was covered with giant insects. Imagine a world where dragonflies are the size of crows and millipedes are as long as cars. Welcome to the Carboniferous Period. Why were insects so enormous during this time? What did oxygen have to do with it? And why did these insects go extinct?

The Carboniferous Period was one of the most transformational periods in the history of Earth. The planet's landmasses were beginning to form the supercontinent of Pangea. Extensive swamps and warm, humid forests dominated the landscape. And giant insects weren't the only huge creatures roaming the planet. There was also a vast array of marine life, like early forms of sharks and a giant amphibian that would reach up to 6 feet long…"

If you find a cockroach that can pull a locomotive…hitch him up!

more dangerous due to the high O2 level and lighting setting the air on fire.

Bill, at surface pressure, I think the 35 percent would be deadly to humans over time. Least, read that somewhere.

Prehistoric earth was a truly alien planet.

@Whackmole9, only if the total air pressure is the same as today and I think it was a lot lower [0.20-0.25 bar], oxygen toxicity occurs at a partial pressure of 0.3 bar so 35% needs a total air pressure more than 0.86 bar to be toxic. I'm not sure how the difference in pressure impacts the flammability though.
