Belodella? tenuiserrata sp. nov.

Holotype: ZPAL CXVI/692 ; S 0 (tr) element (Fig. 5B).

Derivation of the name: Referring to extremely fine denticulation of elements.

Distribution.—Mid−Frasnian of Wietrznia in the Holy Cross Mountains, Poland (see Table 1 and Fig. 4 ).

Figures

Fig. 4. Correlation of studied sections of the Frasnian in the Holy Cross Mountains, Poland and position of conodont samples and ammonoid−bearing horizons. Note that the complete section of the Płucki main trench (extreme left) is drawn in different scale; samples between Pł−25 and Pł−18 come from small trenches. Above is a map of the Wietrznia quarries with locations of the sampled sections; the basal part of the section, with Ancyrodella soluta, has not been sampled because of low frequency of conodont elements (see Racki 1993); provisional zonation based on other Ancyrodella species is shown. Kowala section was measured at the eastern end of the quarry, the highest exploitation level. A. Wietrznia 1d of Racki et al. (1993; Racki and Bultynck 1993). B. Wietrznia 1e. C.
