The Proto Donata or Meganisoptera are an extinct group of the Dragonflies lineage ( Odonata ). They include a well-known representative the giant dragonflies ( Meganeura monyi ) with up to 70 and Meganeuropsis permiana with up to 72 centimeters wingspan and thus the largest flying insects of the earth's history.
The oldest representatives were three species from the Namurium Hagen- porch (about 320 million years old ) in Germany: Namurotypus sippeli (32 cm wingspan ), Erasipteroides valentini and Zessinella SIOPE. The largest found on German territory riesenflüglige Urlibelle is Stephanotypus schneideri from the Stefanium of roach in Halle ( about 295 million years old ), with a wingspan of 45 cm ( Brauckmann & Zessin, 1989).
These animals have lived in the upper Carboniferous before about 320 million years to the late Permian period about 251 million years ago.
