Abstract (in english)
   Despite continuous study and considerably discussion a number of essential problems concerning the Ordovician/Silurian boundary and its stratotype have been lately raised and the new ideas relevant to the Ordovician/Silurian transition continue to be expressed. The new data from well preserved and rich in fauna Chinas 'profiles as well as restudy of the Dob's Linn (Scotland) standard profile caused that a revision to the biostratigraphic definition of the O/S boundary is proposed. According to the newest suggestion the basal of the Silurian is the Akidograptus ascensus Zone which is overlain by the acuminatus Zone. These data are compared with the essential results of the recently investigated profiles from the Leba Elevation (northern Poland) and Holy Cross Mts
