Fig. 4 in Faunal dynamics across the Silurian-Devonian positive isotope excursions (δ C, δ O) in Podolia, Ukraine: Comparative analysis of the Ireviken and Klonk events

Fig. 4. Lithologic and faunal succession through the Silurian–Devonian boundary beds at Dnistrove in the early Klonk Event, with detail of newly proposed Dnistrove Level, against the secular pattern of δ13C (black curve) and δ18O (grey curve) values (after Małkowski and Racki 2009: table 2). Note that the system boundary is placed 0.7 m higher than the tentative positioning given in Małkowski et al. (2009: fig. 6). Onset of the carbon isotope anomaly (SIDECIE), first appearances of the index graptolite and conodont species are shown, as well as the key brachiopod distribution (Baliński 2012; see also Figs. 8, 19, 20), rapid lateral changes of crinoid accumulations, and selected samples.
