  • Acanthodian assemblages from the Eifelian/Givetian boundary beds are discussed in this paper. Th ey were studied at three localities in the Lemovzha river basin. Th e section of the Narva Regional Stage, presented there is considered as the most complete for the Eastern part of the Main Devonian field. The acanthodian assemblage corresponding to the Nostolepis kernavensis zone was diagnosed in the sandstone bed, 1.5 m up from the top of the marls, typical for the Narva Regional Stage. On this basis it is suggested that this part of the section belongs to the Kernave Substage of the Narva Regional Stage. Thus, new data on the acanthodians allow for the Narva/Aruküla boundary on this territory to be defined more percisely.
