About this image:
With a wing span of more than 2 feet, Meganeuropsis may well be the largest insect ever. Similar in appearance to a modern dragonfly, Meganeuropsis had wings up to 29 inches from tip to tip. Meganeuropsis disappeared, along with up to 90 percent of a species of life on Earth, at the end of the Permian.
