趣味知識
Arthropleura is the largest known land arthropod of all time, reaching at least 2 metres (6.5 feet) long.1
It left giant trackways up to 50 centimetres (20 inches) wide, which are fossilized footprints of its many legs.1
Its head had features of both millipedes and centipedes, showing it was a mix of both groups.2
Arthropleura lived in open, sparsely wooded areas near water and may have been able to go on land and in water.1
It was a slow mover, not a fast runner like centipedes, based on its short legs and trackways.2
Some Arthropleura fossils are so well preserved that scientists can see the details of its head and mouthparts using special scanners.2
關於 Arthropleura 最常被問的問題
?How big was Arthropleura?
About 2 metres (6.5 feet) long, possibly up to 2.63 metres (8.6 feet). That makes it the largest known land arthropod of all time.12
?What did Arthropleura eat?
It probably ate dead plants and other detritus, like modern millipedes. It did not have venom fangs or legs for catching prey.5
?Was Arthropleura a dinosaur?
No, it was a giant millipede, not a dinosaur. It lived long before the dinosaurs, from about 344 to 292 million years ago.1
?Could Arthropleura swim?
It may have been amphibious, meaning it could live both on land and in water. It lived in open, sparsely wooded areas near water.1
?How fast could Arthropleura move?
Probably only about 4 km/h (2 mph), a slow walking pace. This is a guess: it was a giant millipede with short legs, and its trackways show it did not hurry.5
?Did Arthropleura have a head?
Yes, and scientists recently used special scanners to see its head in detail. It had antennae, mandibles, and two pairs of maxillae.2
?When did Arthropleura go extinct?
It died out around 292 million years ago, during the early Permian period.1
?Where did Arthropleura live?
It lived in what is now Europe and North America, in open, sparsely wooded forests near water.1
?Is Arthropleura related to centipedes?
It is a millipede, but its head has features of both millipedes and centipedes, showing it was a mix of both groups.5
?How much did Arthropleura weigh?
One large fossil suggests it weighed about 50 kilograms (110 pounds), as heavy as a small human.1
迷思破解王
迷思： Arthropleura was a giant centipede that hunted other animals.
真相： Arthropleura was actually a millipede, and it was likely a slow plant-eater, not a predator.2
