The Largest Arthropod in History Discovered: Fossils Reveal Nine-Foot-Long Millipede!

ST. PAUL, MN – Imagine a world where colossal creatures roamed the Earth, towering over today’s fauna. During the Carboniferous period, between 300 million and 360 million years ago, this was a reality. Among the giants was Arthropleura, a remarkable nine-foot-long arthropod that holds the title of the largest of its kind to ever exist.

Unveiling the Giant: A Look at Arthropleura’s Discovery

For years, the specifics of Arthropleura’s face remained a mystery, as scientists struggled to piece together its appearance from headless fossil remnants found since the 1800s. However, recent discoveries in Montceau-les-Mines, France, have shed new light on this ancient monster. Researchers unearthed two juvenile fossils, each measuring less than two inches long, providing the first glimpse of what the head of Arthropleura looked like.

The reconstructed head features a rounded shape adorned with two antennae, a small mandible tucked beneath, and eyestalks extending from the sides. This significant find not only reveals the creature’s appearance but also helps clarify its evolutionary placement.

A Unique Blend: Anatomy and Features of Arthropleura

Arthropleura is part of a diverse group of invertebrates that includes crustaceans, spiders, and insects. The confusion surrounding its classification has fueled debate among scientists since its discovery in 1854. Recent examinations of the juvenile fossils revealed a fascinating mix of characteristics: it exhibits a millipede-like body structure yet features a head reminiscent of a centipede. Notably, the arthropod had two pairs of legs per body segment—44 pairs in total—differentiating it from centipedes, which possess only one pair.

Among its most intriguing features are the eyestalks, a trait not found in any current millipede or centipede. These stalks bear a resemblance to those of crabs, suggesting that Arthropleura may have had an aquatic larval stage before transitioning to land as an adult.

Breathing Giants: The Role of Oxygen in Arthropleura’s Size

This creature was not the fearsome predator one might expect. Researchers propose that Arthropleura was more akin to a giant herbivore of its time, feeding primarily on decaying plant matter. Its anatomy hints at a slow-moving lifestyle, lacking the hunting appendages typical of modern centipedes.

Arthropleura thrived in an era when oxygen levels were significantly higher than today—around 30% compared to our current 21%. This oxygen-rich environment likely played a crucial role in the size of many arthropods during the Carboniferous period. Insects, such as Arthropleura, respire through tiny openings that allow oxygen to circulate through their bodies. With more oxygen available, they could grow to sizes that seem almost fantastical today.

Our Past Holds Many Mysteries

While the revelation of Arthropleura’s head marks a major milestone in paleontology, it also opens the door to further discoveries. Future fossil finds could provide insights into its breathing mechanisms and more about its adult forms. Understanding how Arthropleura fit into the broader arthropod lineage will continue to intrigue scientists.

As our knowledge expands, the story of Arthropleura reminds us that the past holds many mysteries waiting to be unraveled. Each discovery invites us to reconsider what we know about the ancient world and the extraordinary creatures that once walked—or scuttled—our planet.
