Archipolypoda is assigned its own class in the Treatise on Invertebrate Paleontology, but are commonly found classified under the Diplopoda (millipedes). They differ from Diplopoda, however, with less coalesced segments where the prozonites retain medially divided sternum with pair of legs. The head is apparently larger than the body segments, and equipped with large compound eyes. Fine examples are known from the Mazon Creek lagerstätte.
