Answer:
Dragonfly
Explanation:
The Carboniferous is a geological era and system that span 60 million years from the end of the Devonian Era 358.9 million years ago, to the start of the Permian Period, 298.9 Mya.
Meganeura is a genus of Carboniferous-era extinct insects (about 300 million years ago) due to decline in atmospheric oxygen and the rise of birds contributed to their demise, which resembled and are related to the present-day dragonflies.
Dragonflies act as top predators in ponds without fish and help to control populations of mosquitos and other flies.
Hence, draginflies are the replacment of Meganeura in Carboniferous Period.
