Five trilobite assemblages are distinguished within the Lower Devonian deposits of the Novaya Zemlya Archipelago (USSR). The assemblages may be grouped into three major evolutionary stages which correspond to the early Lochkovian, late Lochkovian to Pragian, and to Zlíchovian-Eifelian intervals. Marked interregional affinities between the assemblages of Novaya Zemlya and those of Urals, Altai-Sayan regions, Barrandian, North Africa, and especially Arctic regions of North America demonstrate the correlative value of trilobites particularly in the lower Lochkovian and Pragian.
