Knowra Meganeura Meganeura Meganeura is an extinct genus of giant griffinfly-like insects from the Late Carboniferous, about 300 million years ago. Its large wings made it among the biggest known flying insects.
Meganisoptera : An extinct order of large, dragonfly-like insects that lived from the Carboniferous to the Permian. Meganeura belongs to this broader group, often called griffinflies.
Meganeura monyi : An extinct species of giant griffinfly from the Late Carboniferous, known from fossils found in France. It is the type species that anchors the genus Meganeura.
Insect thorax : The middle body region of an insect, bearing the legs and wings. Its flight muscles would have driven Meganeura’s paired wings.
Insect gigantism : The evolution of exceptionally large body sizes in insects, especially in the fossil record. Meganeura is a prominent example whose size prompts questions about biological limits.
Insect flight : The ways insects generate and control aerodynamic forces to fly. Meganeura’s enormous wings were powered by insect flight anatomy and mechanics.
Meganeura permiana : An extinct species assigned to Meganeura, described from Permian fossils. Its placement illustrates the genus’s reported fossil range beyond the Carboniferous.
Aerodynamics : The study of how air moves and how it exerts forces on objects. The forces on Meganeura’s broad wings governed lift, drag, and flight performance.
Atmospheric oxygen : The concentration of oxygen in a planet’s atmosphere at a given time. Carboniferous oxygen levels are debated as a possible constraint on giant insect size.
Insect wing : A paired, vein-supported appendage that enables flight or other functions in insects. Wing shape and vein patterns are central to identifying fossil griffinflies.
Meganeuropsis : An extinct genus of giant griffinflies from the Permian, including some of the largest known flying insects. It is a close relative often confused with Meganeura and reached comparable or greater sizes.
