Abstract (in english)
   Until recently Upper Silurian graptolites were rarely known from the South Tien Shan area of central Asia (former USSR). Detailed mapping and biostratigraphic studies have revealed a complete succession of late Ludlow and Pridoli graptolite-bearing mudstones and siltstones from the Kursala Fm., a stratigraphical unit which is preserved as a part of an extensive nappe structure in the northern foothills of the Alai Range, Kirgizia. A high resolution graptolite zonation, comparable with that of the Upper Silurian of the Prague Basin is established in the study region. Graptolite biostratigraphic data obtained from the upper Ludlow (Ludfordian) beds of the Kursala Fm. provide additional information about the graptolite assemmblages which precede the appearance of the early Pridoli monograptids. The global correlative potential of the internationally recognized Pridoli graptolite biozones (the parultimus, ultimus, branikensis and some levels within the transgrediens s.l.
   Biozone) is elaborated. Sixteen monograptid species (two new: M.petri and M.tumultuosus) are described
