アースロプレウラ (Arthropleura アルスロプレウラ) is the huge class arthropoda which inhabited the forest of the Carboniferous period in the Paleozoic era. For an arthropod friend, it is thought with the largest thing along with kind of the eurypterid in history.

A form and classification
I did the structure that a metamere led to a lot (at least 20 sections) of the approximately similar form. The full length reaches 3 meters from 2 meters; the width is 45 centimeters. A fossil is found in Nova Scotia, Illinois, Ohio, each place including Pennsylvania. Because the complete specimen is not provided, there are many mysteries, but I resemble a centipede and the millipede of Myriapoda, and it is thought that these are near in detail. The structure of the leg includes a unique point, and there is the opinion raising an original rope, and the classification list of this rope follows it, but there is the opinion to include under the millipede rope.
Habits
The centipede is eating meat to prey on a small animal, and the millipede is a sloppy meal, but it is thought that アースロプレウラ was plant food. The flexible health that many metameres led to was suitable to move the forest. Because it was a big animal, the fossil of the trace that the weight crawled heavily is known in each place.
Approximately 35% and a high opinion and vertebrate begin evolution in the land the atmospheric oxygen density in those days, and, as the cause that there were many class arthropoda (including the insect) which are huge like アースロプレウラ and an extinct dragonfly of the genus Meganeura in a Carboniferous period, the opinions which there was few an animal preying on these are advocated by the major breeding of the fern guild because it was about time when there is not it in the interval either. For the Permian beginning, anything huge arthropod became extinct. As for the cause, forest environment same as a Carboniferous period disappears with the change of the climate not the thing due to the predatory animal, and it is said that a plant becoming the food is a lost thing.
