Meganisoptera is an extinct order of very large to gigantic insects, occasionally called griffinflies. The order was formerly named Protodonata, the "proto-Odonata", for their similar appearance and supposed relation to modern Odonata (damselflies and dragonflies). They range in Palaeozoic (Late Carboniferous to Late Permian) times. Though most were only slightly larger than modern dragonflies, the order includes the largest known insect species, such as the late Carboniferous Meganeura monyi, Megatypus, and the even larger early Permian Meganeuropsis permiana, with wingspans of up to 71 centimetres (28 in).
The fore and hind wings are similar in venation (a primitive feature) except for the larger anal (rearwards) area in the hind wing. The fore wing is usually more slender and slightly longer than the hind wing. Unlike the true dragonflies, the Odonata, they had no pterostigma, and a somewhat simpler pattern of veins in the wings.
Most specimens are known from wing fragments only; with only a few as complete wings, and even fewer (of the family Meganeuridae) with body impressions. These show a globose head with large dentate mandibles, strong spiny legs, a large thorax, and long and slender dragonfly-like abdomen. Like true dragonflies, they were presumably predators.
It’s hard to imagine anything roaming the earth before the dinosaurs. As big and ferocious as we know they were, scientists have found bones of animals that were older — and weirder — than even the stubby-armed Tyrannosaurus Rex. Most were overgrown fish with a chip on their shoulders, but all were as crazy as it gets. Please Subscribe by clicking the red subscribe button! Have an idea for a future video?

Meganeura is a genus of extinct insects from the Carboniferous period, which resembled and are related to the present-day dragonflies. With wingspans of up to 65 cm, M. monyi is one of the largest known flying insect species; the Permian Meganeuropsis permiana is another. Meganeura were predatory, and fed on other insects. Fossils were discovered in the French Stephanian Coal Measures of Commentry in 1880. In 1885, French paleontologist Charles Brongniart described and named the fossil "Meganeura", which refers to the network of veins on the insect's wings. Another fine fossil specimen was found in 1979 at Bolsover in Derbyshire. The holotype is housed in the Muséum national d'histoire naturelle, Paris. This video is targeted to blind users.
