This insect lived 285 million years ago, in the early Permian period. During this time, the atmosphere contained 30% oxygen, much higher than the 21% oxygen it contains today. These high oxygen levels allowed insects to reach enormous sizes. This particular specimen had an 8 inch wingspan, but closely related species grew much larger. Meganeuropsis permiana, the largest species in this group, had a whopping 28 inch (71 cm) wingspan. These species belonged to a group called the Meganisoptera and were probably close relatives of modern dragonflies. We know that they were not true dragonflies because of differences in the shape of their wing veins.
Species: Typus whitei
This fossil, is the type specimen for T. whitei and is from the Hermit Shale of Lower Permian time (~280 million years old). This nearly complete fore-wing is from an early and much larger insect simlar to a dragonfly.
