在大约3亿年前的石炭纪,气候温暖湿润,沼泽和森林遍布各地。高大的乔木享受着上层空间的阳光雨露,而以蕨类植物为主的灌木则占据了森林的下层领地。此时,恐龙尚未出现。在广袤的天空中,有史以来体形最为庞大的飞行昆虫“巨脉蜻蜓”掌握着生杀大权。巨脉蜻蜓的飞行时速超过32千米。它们的颌部能够将包括小型爬行动物在内的猎物撕成碎片。 About 300 million years ago in the Carboniferous, warm and humid climate, marsh and forests all over. Tall trees enjoy the sunshine of the upper space, while the ferns dominated the shrubs occupy the lower reaches of the forest. At this point, dinosaurs have not yet appeared. In the vast sky, the largest ever flying insect “giant pulse dragonfly” holds the power to kill and kill. Giant dragonfly flight speed of more than 32 km. Their jaws can tear prey, including small reptiles, into pieces.
