“About 300 million years ago, long before the first dinosaurs appeared, a different type of oversized critter inhabited Earth: giant insects. Scientists suspect bugs grew bigger then because the atmosphere contained more oxygen than it does now. For example: Wings of one ancient dragonfly measured almost as long, tip to tip, as a Little League baseball bat. Alas, the giant insects didn’t last, and a modern dragonfly can fit comfortably inside a Wiffle ball. In a new study, researchers say the reign of mammoth insects ended when hungry, flying predators came along about 150 million years ago.” (Source) Β To read more about prehistoric insects click here and here.

  1. I’m happy those flying predators came along and ate the giant insects! I love to see dragon flies but not the size of baseball bats!!!!!!!!!!
