Prehistoric myriapod genera

Pneumodesmus newmani is a species of myriapod. It is originally considered that it lived during the late Wenlock epoch of the Silurian period around . However, a 2017 study dates its occurrence based on zircon data analysis as the Early Devonian (Lochkovian). Although the 2023 study confirmed the age identification of the 2004 study through palynological, palaeobotanical and zircon analyses incorporating newly discovered additional data, this is based on adjacent structurally separated block with different stratigraphy and sedimentology to the block with fossil site it was discovered, and it i

Eoarthropleura was a genus of millipede-like creatures which lived between the Late Silurian and Late Devonian periods. It reached in length. Fossils, mainly of cuticle fragments, have been found in Europe (Rhineland-Palatinate, Germany and Shropshire, England) and North America (New York, USA and New Brunswick, Canada). It is the earliest known member of the Arthropleuridea, and the oldest known terrestrial animal of North America.

Anbarrhacus is an extinct genus of millipede in the family Platyrhacidae known from a fossil found in North America. There is one described species in the genus, Anbarrhacus adamantis, which is one of three millipedes described from Mexican amber.
