Top Predators of Their Time: These giants hunted smaller insects in the skies, using their massive wings and sharp eyesight to dominate the prehistoric world.

Fossil Finds: Their fossils, found in Europe and North America, reveal stunning wing patterns and help scientists understand insect evolution.

Gone But Not Forgotten: They vanished around 250 million years ago after a mass extinction but remain a symbol of prehistoric insect power.
