Fig. 1. Geological setting of the type locality of Ferussina petofiana. A = Position of the Hațeg Basin (rectangle; HB) within Romania. B = Simplified geological map of the Hațeg Basin, highlighting the distribution of the uppermost Cretaceous continental deposits (shades of green). Legend: 1 – surrounding metamorphic basement, 2 – units of the sedimentary basin infill (mostly marine), 3-5 – fossiliferous Maastrichtian continental deposits, with 3 – Sînpetru Formation, 4 – Densuș-Ciula Formation (v – volcaniclastic beds), and 5 – Sînpetru Formation-correlative units (see CSIKI-SAVA et al. 2016), 6 – Quaternary cover, 7 – sites with gastropod assemblages (a – SCHAFARZIK 1909, b – RĂDULESCU et al. 1976, c –ANTONESCU et al. 1983, d –GRIGORESCU et al. 1985, e – PANĂ et al. 2002, f – CSIKI et al. 2008, g – VASILE et al. 2011; see text for details), 8 – site K3 of Vălioara, the type locality of Ferussina petofiana (from BOTFALVAI et al. 2021). C = Synthetic lithological column near site K3 (marked by red arrow), modified from BOTFALVAI et al. (2021). Lithofacies abbreviations: BChD – braided channel deposits, mainly conglomerates, ChL – sandstone channel lag, SSp – sandstone sheet-splay, PdFP – poorly drained floodplain deposits, mainly grey-greenish silts and muds, WdFP – well-drained floodplain deposits, mainly red silts and muds. For more details, see BOTFALVAI et al. (2021). D. View of site K3 in the Pârâul Neagului ravine, located in grey-greenish fine-grained floodplain deposits (near handle of hammer). E.
