Fig. 2. Simplified lithostratigraphic profile of the Polonez Cove Formation, with lithological profile of the Siklawa Member at Mazurek Point where investigated fossils were collected. The arrow marks the mudstone interval where the majority of the specimens of Pholadidea gradzinskii sp. nov. described in this paper was collected. The lithostratigraphy after Birkenmajer (1983), Porębski and Gradziński (1987), Birkenmajer (2001), Troedson and Smellie (2002). Dating of the units after Smellie et al. (1984), Birkenmajer (1989), Dingle et al. (1997), Dingle and Lavelle (1998), and Troedson and Smellie (2002). The lithological profile of the Siklawa Member at Mazurek Point partially adapted from Gaździcki et al. (1982).
