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] Distinguishing characteristics include relatively large eyes with densely packed ocelli (sometimes interpreted as compound eyes), and modified leg pairs on the 8th body ring.[3][4] Some species had prominent spines while others had a flattened appearance.[3][5]

Classification[edit]

The Archipolypoda as currently recognized consists of four orders,[6] many with monotypic families and genera, as well as five species of uncertain placement (incertae sedis).[3][7]
