Arthropleura (Greek for 'jointed ribs') is an extinct genus of massive myriapod that lived in what is now Europe and North America around 345 to 290 million years ago, [2] [4] from the Viséan stage of the lower Carboniferous Period to the Sakmarian stage of the lower Permian Period.
One notable example was Arthropleura, the biggest bug ever known at up to 10-1/2 feet (3.2 meters) long, inhabiting what is now North America and Europe. ... Having two pairs of legs by segments ...
The extinct Arthropleuridea was long considered a distinct myriapod class, although work in the early 21st century established the group as a subclass of millipedes. [29] [30] [31] Several living orders also appear in the fossil record. Below are two proposed arrangements of fossil millipede groups. [9] [14] Extinct groups are indicated with a ...
Arthropleuridea is an extinct subclass of myriapod arthropods that flourished during the Carboniferous period, having first arisen during the Silurian, and perishing in the Early Permian. [1] Members are characterized by possessing diplosegement (fused "double segments", as in modern-day millipedes ) paranotal tergal lobes separated from the ...
Archipolypoda is an extinct group of millipedes known from fossils in Europe and North America and containing the earliest known land animals. [1] The Archipolypoda was erected by Scudder (1882) [2] but redefined in 2005 with the description of several new species from Scotland. [3]
Cowiedesmus is an extinct millipede genus described from Scotland, [1] and is considered as earliest known land animals alongside Pneumodesmus from same formation. [2] It is originally considered that it is from the middle Silurian, a 2017 study suggested that the geological formation it contains actually appears to be from the Early Devonian instead. [3]
The Xyloiuloidea is an extinct superfamily of fossil millipedes of uncertain placement within the Juliformia. Known from the Lower Devonian to the Upper Pennsylvanian, Xyloiuloidea consists of four families and several genera. The group was formerly considered a suborder of Spirobolida, but newly discovered species in 2006 required a ...
Archispirostreptus gigas, known as the giant African millipede, shongololo or Bongololo, is the largest extant species of millipede, growing up to 33.5 centimetres (13.2 in) in length, 67 millimetres (2.6 in) in circumference.
