During the Carboniferous Period, about 300 million years ago – long before the dinosaurs appeared – Earth looked completely different. The atmosphere had much higher oxygen levels, which allowed insects and other arthropods to grow to enormous sizes. Dragonflies with wingspans over 70 cm (bigger than many birds) flew through the skies, while giant millipedes over 2 meters long crawled across the swampy forests. This was a strange, humid world dominated by massive insects and dense fern forests. It was also the time when the first reptiles appeared and huge coal deposits began to form from the buried plant material. A truly alien-looking Earth… before the age of dinosaurs even began. #scary #prehistoric #fyp #goviral #targetaudience
