Are Griffinflies Extinct?

Meganisoptera, commonly known as griffinflies, is an extinct order of very large to gigantic insects that resembled modern dragonflies and damselflies (Odonata). Formerly named Protodonata, meaning "proto-Odonata," this order existed during the Paleozoic era, specifically from the Late Carboniferous to the Late Permian periods, approximately 317 to 247 million years ago. These impressive insects thrived in a swampy, green world before the rise of dinosaurs, filling the skies with their massive presence.

Griffinflies boasted extraordinary wingspans, reaching up to 71 centimeters (28 inches), making them some of the largest known insects ever. The genus Meganeuropsis, particularly Meganeuropsis permiana, holds the record as the largest known insect, showcasing the immense scale these creatures achieved. Another notable genus, Meganeura, lived around 300 million years ago and contributed to the awe-inspiring reputation of griffinflies.

Despite their dragonfly-like appearance, griffinflies were more primitive and belonged to a distinct order separate from true dragonflies. Their lifestyle and lifecycle closely mirrored those of modern Odonata, but their fossil record is relatively brief. The oldest known winged insect, Delitzschala bitterfeldensis, dates back to about 325 million years ago and is part of the Meganisoptera order.

Griffinflies like Meganeura monyi and Meganeuropsis permiana are celebrated as some of the most magnificent and largest insects to have ever existed. Their existence during the Late Carboniferous to Late Permian periods highlights a fascinating chapter in the history of life on Earth, showcasing the incredible diversity and scale of prehistoric insects.

How Long Did Meganisoptera Last?

Meganisoptera is an extinct family of large, predatory insects, resembling today's dragonflies and damselflies, that thrived from the Late Carboniferous to the Late Permian, approximately 317 to 247 million years ago. The most notable member of this group is Meganeuropsis, which is recognized as the largest known insect, with a wingspan of about 28 inches and a body length of around 17 inches. Meganeuropsis originated from the Early Permian Wellington Formation in North America.

Initially discovered in France, Meganeura, another genus within the Meganisoptera order, dates back to the Late Carboniferous, around 300 million years ago. Collectively, these giant dragonfly-like insects dominated the ecosystems of the Paleozoic era, particularly during the late Carboniferous and into the early Permian. They are commonly referred to as griffinfly or, incorrectly, giant dragonflies. The order was previously known as Protodonata due to its close relation to modern odonatans.

However, Meganisoptera and all its members faced extinction at the end of the Permian period around 250 million years ago, amid one of the most significant mass extinction events in Earth’s history, which led to the demise of many large species. Their fossil record, though limited, provides vital insights into insect evolution and the prehistoric environment. Despite their brief existence, Meganisoptera remains a fascinating subject for paleontologists studying the history of life on Earth.

Why Did Meganeura Go Extinct?

Meganeura, a giant dragonfly-like insect from the Carboniferous period, became extinct at the end of the Permian period, around 250 million years ago, likely due to changing environmental conditions and fierce competition with evolving species. This extinction coincided with the Permian-Triassic crisis, which wiped out approximately 90% of Earth’s species. It is believed that declining oxygen levels contributed to the extinction, diminishing from the higher levels present during the time Meganeura thrived.

During the Carboniferous era, Meganeura boasted a wingspan of about 75 centimeters and had sophisticated compound eyes akin to modern insects. Despite their size and dominance in North America and Europe, sharing habitats with giant amphibians and reptiles, they could not survive the declining atmospheric conditions of the Late Permian, which featured notably lower oxygen compared to 300 million years prior.

Scientists assert that although Meganeura could flap their wings faster in lower density atmospheres, the changing atmospheric composition ultimately rendered them incapable of sustaining their large body sizes. This extinction exemplified the relationship between atmospheric oxygen levels and insect size throughout evolutionary history, revealing that the tracheal breathing system of insects imposes constraints on their maximum size.

Meganeura is regarded as one of the largest known flying insects, first discovered in France in 1880 and is classified within the extinct order Meganisoptera. Its eventual extinction, alongside other large insects, illustrates the broader ecological shifts taking place during this tumultuous period in Earth's history.

What Is The Biggest Bug To Ever Exist?

Scientists recently confirmed that a fossil discovered in 2018 on a northern England beach belongs to a giant millipede known as Arthropleura, which is considered the largest bug to ever exist. This prehistoric creature could grow nearly 9 feet long and weigh over 100 pounds, feeding on decaying plants approximately 326 million years ago. The fossil sheds light on its previously unknown head structure, which was not available in earlier fossil remains that lacked heads.

Additionally, the largest known insect ever was Meganeuropsis permiana, a massive dragonfly from the late Permian era, which had a wingspan of about 28 inches and showcased the incredible diversity of insects that once populated the Earth. Insects, being a type of arthropod, are the most abundant group of multicellular organisms, with over a million species identified to date. The quest for the heaviest insect includes contenders like the larval stage of the goliath beetle, Goliathus goliatus, which can weigh around 4. 1 ounces and measure 11. 5 cm.
