The wingspan of an average adult male Pteranodon was 5.6 m (18 ft). Adult females were much smaller, averaging 3.8 m (12 ft) in wingspan. [18] A large specimen of Pteranodon longiceps, USNM 50130, is estimated to have a wingspan of 6.25–6.5 m (20.5–21.3 ft), body length of 2.6 m (8.5 ft) and body mass of 50 kg (110 lb).
The genus belongs to the Meganeuridae, a family including other similarly giant dragonfly-like insects ranging from the Late Carboniferous to Middle Permian. With single wing length reaching 32 centimetres (13 in) [ 1 ] and a wingspan about 65–75 cm (2.13–2.46 ft), [ 2 ] [ 3 ] [ 4 ] M. monyi is one of the largest-known flying insect species .
