Meganeura was a giant dragonfly-like insect that lived about 300 million years ago. It had a wingspan as wide as a small bird and was one of the biggest flying insects ever. It hunted other insects in open forests and near lakes.12

ເລື່ອງເທ່ໆ

ເລື່ອງໜ້າຮູ້ມ່ວນໆ

1

Meganeura's wingspan was about 65 to 75 centimetres (2.1 to 2.5 feet), bigger than any dragonfly alive today.1

2

Its huge compound eyes met along the top of its head, giving it excellent vision to spot prey against the sky.12

3

Meganeura was a 'hawker' that patrolled open areas and above the treetops, not a fast zigzag flyer through dense forests.2

4

Its legs had large spines that formed a 'flying trap' to grab insects in mid-air.1

5

Scientists think Meganeura spent a lot of time perching because its large body made breathing difficult during flight.1

6

The first Meganeura fossil was found in a coal mine in Commentry, France, in 1880.1

7

Only one species of Meganeura is considered valid today: Meganeura monyi.1

ຄຳຖາມທີ່ຖືກຖາມຫຼາຍທີ່ສຸດກ່ຽວກັບ Meganeura

?How big was Meganeura?

Meganeura had a wingspan of about 65 to 75 centimetres (2.1 to 2.5 feet) and a body length up to 43 centimetres (1.4 feet). It was one of the largest flying insects ever.14

?Could Meganeura fly fast?

No, it could not make sudden direction changes like modern dragonflies. It was a 'hawker' that patrolled open areas and above treetops, flying steadily rather than zigzagging.12

?What did Meganeura eat?

Meganeura was a predator that ate other insects. It used large spines on its legs to trap prey in mid-air, like a flying trap.14

?Is Meganeura a dinosaur?

No, Meganeura is not a dinosaur. It was a giant dragonfly-like insect that lived about 300 million years ago, long before dinosaurs evolved.1

?When did Meganeura live?

Meganeura lived during the Late Carboniferous period, about 300 million years ago.1

?Why was Meganeura so big?

Scientists think the high oxygen levels in the Carboniferous air may have helped it grow so large, but they are not sure. Another idea is that there were no big flying predators back then.1

?Did Meganeura have good eyesight?

Yes, it had huge compound eyes that met along the top of its head, giving it excellent vision to spot prey against the sky.12

?Where was Meganeura found?

The first Meganeura fossil was found in a coal mine in Commentry, France, in 1880.1

?How much did Meganeura weigh?

Estimates vary a lot, from about 18 grams (0.04 pounds) up to 100 to 150 grams (0.22 to 0.33 pounds). Scientists are not sure of the exact weight.1

?Could Meganeura swim?

No, Meganeura was a flying insect that lived near water but did not swim. It probably perched on plants and patrolled open areas for prey.12

ໄຂຄວາມເຊື່ອຜິດ

ຄວາມເຊື່ອຜິດ: Meganeura could fly as fast and agile as modern dragonflies.

ຄວາມຈິງ: Meganeura could not make sharp turns like modern dragonflies because its wings lacked certain joints. It was a slower, gliding hunter.12
