The fossil record of this taxon (not abundant in annelids overall because this taxon lacks a mineralized skeleton) formerly included Palaeocampa anthrax Meek & Worthen, 1865 from the Late Carboniferous site of Montceau-les-Mines.^[2] However, this genus was redescribed as an aysheaiid lobopodian in 2025.^[3]
