NOTE: MOST FACTS HERE ARE BASED ON VERY CLOSELY RELATED MEGA DRAGONFLIES, AS MEGANEURA IS POORLY PRESERVED. Thank you for reading this, and (hopefully) not criticizing me.
Meganeura was a gigantic dragonfly that was almost the size of an eagle. It had a two foot wingspan, and its eyes were larger relative to its body size than that of modern-day dragonflies. Meganeuras had special spines on their legs that helped it to snatch small amphibians.
