Extended data

A primitive dragonfly fossil dating from 2 million years ago was found in the northwestern margin of Junggar Basin in China. This newly discovered primitive dragonfly has a single wing length of 11 to 12 mm and a wing spread width of 21 mm, making it the second largest known dragonfly fossil in Mesozoic in China.

In the Jurassic Daohugou fossil layer in Ningcheng, Inner Mongolia, a nearly intact fossil of the front wing of a dragonfly was also found, with a single wing length of 17.6 mm and a width of 14.3 mm. Based on this, it can be inferred that the wing spread of this dragonfly is 225 mm, which is the largest known species of Odonata in China and the fourth largest dragonfly in the world.
