Included here are some of the earliest myriapods. Some, like the spiny Acantherpestes (above), grew to very large size, others were more normal in dimensions. Although given their own class in the Treatise, the Archipolypoda are also often classified under the Diplopoda (millipedes). They differ however in that the segmental elements are less coalesced, 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. The characteristics of the mouthparts and location of the gonopore are unknown.
The best known specimens are from the Mazon Creek lagerstätte. Many forms are poorly known.
