Meganisoptera is an extinct order of large dragonfly-like insects, informally known as griffenflies or (incorrectly) as giant dragonflies. The order was formerly named Protodonata , the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata ( damselflies and dragonflies ).
Meganeura is a genus of extinct insects from the Late Carboniferous (approximately 300 million years ago). It is a member of the extinct order Meganisoptera, which are closely related to and resemble dragonflies and damselflies (with dragonflies, damselflies and meganisopterans being part of the broader group Odonatoptera).

Meganeuropsis is an extinct genus of griffinfly, order Meganisoptera, known from the Early Permian Wellington Formation of North America, and represents the largest known insect of all time. Meganeuropsis existed during the Artinskian age of the Permian period , 290.1–283.5 mya . [ 1 ]
Stylized diagram of insect digestive tract showing malpighian tubule, from an insect of the order Orthoptera. The first section of the alimentary canal is the foregut (element 27 in numbered diagram), or stomodaeum. The foregut is lined with a cuticular lining made of chitin and proteins as protection from tough food.
Meganeuridae is an extinct family of griffinfly in the order Meganisoptera. There are more than 20 genera and 50 described species in Meganeuridae. This family contain the genus Meganeuropsis, which is one of the largest known insects. [1] [2]
The Odonatoptera are a superorder (sometimes treated as an order) of ancient winged insects, placed in the probably paraphyletic group Palaeoptera.The dragonflies and damselflies (which are placed in the subgroup Odonata) are the only living members of this group, which was far more diverse in the late Paleozoic and contained gigantic species, including the griffinflies (colloquially called ...
Most Meganisoptera (especially Meganeura) reconstructions on Wikipedia are based on traditional reconstructions with discontinuous eyes. However, this reconstruction is based on a poorly preserved fossil of a insect from probably related group, called Erasipteroides .
