Article: The distribution of Lower Carboniferous goniatite faunas in relation to suggested continental reconstructions for the period

The geographic distribution of Lower Carboniferous goniatite faunas (referred to seven faunal assemblages) are shown located on a modem map and on a suggested repositioning of the continents in Lower Carboniferous times. Except at the top of the Visean the faunas generally are cosmopolitan and the reconstruction provides satisfactory migration routes along shallow seaways bordering continental masses. The reconstruction narrows the latitudinal range of the faunas and places them more symmetrically with regard to the postulated equator except for certain sites in Siberia. These are sufficiently anomalous as to question the placing of the Siberian Shield.
