Abstract

Arthropleura is a genus of giant myriapods that ranged from the early Carboniferous to Early Permian, with some individuals attaining lengths >2 m. Although most of the known fossils of the genus are disarticulated and occur primarily in late Carboniferous (Pennsylvanian) strata, we report here partially articulated Arthropleura remains from the early Carboniferous Stainmore Formation (Serpukhovian; Pendleian) in the Northumberland Basin of northern England. This 76 × 36 cm specimen represents part of an exuvium and is notable because only two comparably articulated giant Arthropleura fossils are previously known. It represents one of the largest known arthropod fossils and the largest arthropleurid recovered to date, the earliest (Mississippian) body fossil evidence for gigantism in Arthropleura, and the first instance of a giant arthropleurid body fossil within the same regional sedimentary succession as the large arthropod trackway Diplichnites cuithensis. The remains represent 12–14 anterior Arthropleura tergites in the form of a partially sand-filled dorsal exoskeleton. The original organism is estimated to have been 55 cm in width and up to 2.63 m in length, weighing c. 50 kg. The specimen is preserved partially in three dimensions within fine sandstone and has been moderately deformed by synsedimentary tectonics. Despite imperfect preservation, the specimen corroborates the hypothesis that Arthropleura had a tough, sclerotized exoskeleton. Sedimentological evidence for a lower delta plain depositional environment supports the contention that Arthropleura preferentially occupied open woody habitats, rather than swampy environments, and that it shared such habitats with tetrapods. When viewed in the context of all the other global evidence for Arthropleura, the specimen contributes to a dataset that shows the genus had an equatorially restricted palaeogeographical range, achieved gigantism prior to late Paleozoic peaks in atmospheric oxygen, and was relatively unaffected by climatic events in the late Carboniferous, prior to its extinction in the early Permian.

It's a millipede, so it's more likely to ponderously pounce on and consume an overripe orange than hunt other critters.

Even a tiger has to sleep sometimes.

Millipedes are herbivores.
They eat damp or decaying wood particles. They also eat decaying leaves and other plant material. If their habitat starts to dry out, millipedes will attack living plants. They can get moisture from the green leaves and soft roots.

Well, that's some comfort.

Also rather unlikely that a species of millipedes, carnivorous or not, of approximately my weight would have survived from the Carboniferous until the present day without someone noticing.

Unless it's been hiding under your couch the whole time....

I really need to vacuum under that couch more frequently.

That's probably the best thing. According to one source, it will weigh less with a vacuum...

If someone feels a strong sexual attraction to juvenile millipedes, should we call them a millipedophile?

Oh thank goodness. :lol: But you never know, deer and squirrels eat bird chicks. Squirrels eat other vertebrates, mollusks, and insects. Maybe the millipede opportunistically ate Paleozoic tigers. :teef:

And as it's a fossil we can conclude it's not a thoroughly modern millipede.
