Amphiaspis argo is the type species of the cyathaspidid taxon Amphiaspidida, and of the family Amphiaspididae.[1] Its fossils are restricted to early Emsian-aged marine strata of the Taimyr Peninsula, Early Devonian Siberia. A. argo, as with all other amphiaspidids, is thought to have been a benthic filter feeder that lived on top of, or buried just below the surface of the substrate of hypersaline lagoon-bottoms.
