Abstract (in english)
   The goal of this paper is to document the late Ludlow Lau event for the first time from the larger peri - Gondwana area. In Bohemia, we recognize the start of the ä 13 C excursion within a characteristic brachiopod bed dominated by Dayia minor in the upper part of Neocucullograptus kozlowskii graptolite zone (late Polygnathoides siluricus conodont zone). In the upper Kopanina Formation, this level is just below a sequence boundary underneath grey crinoidal limestones bearing the Ananaspis fecunda OE Cyrtia postera Community (= Monograptus latilobus graptolite assemblage zone). The ä 13 C values reach a maximum (+4,6 %o) within the lower part of these strata. Underneath this sequence boundary several extinctions and faunal changes have been observed in different groups. The faunal turnovers presumably have been caused by a combination of changes in climate, sea level and sedimentation..
