Material: 1 specimen, only right valve (no. 23504- BBU-MPS) .

Description: Lower valve is conical, 50 mm in length and with a diameter equal to 35 mm. The triangular ligamental ridge (L) is wide and short, having its end clearly truncated ( Fig. 8k ). The first pillar (P1) is wide and short, with the same length as ligamental ridge. The second pillar (P2) is longer than the first pillar (P1), and is slightly pinched at the base with a head oval-elongated, curved anteriorly ( Fig. 8k ).

Remarks: Vaccinites sulcatus is very similar to Vaccinites archiaci but differs from the latter species by its wide and shorter ligamental ridge. In Vaccinites archiaci the ligamental ridge is thin and longer than first pillar (P1).

Age and distribution: Santonian-early Campanian in Albania ( Peza, 1992, 1998), Austria ( Steuber, 2001), Croatia ( Polšak and Mamuzic, 1969), Italy (Caffau et al., 2004), France ( Astre, 1962) Romania (Todiriță- Mihăilescu, 1966; Lupu, 1969, 1976), Slovenia ( Pleničar, 1961), and Turkey ( Özer, 1998); Campanian-Maastrichtian in Croatia ( Polšak and Mamuzic, 1969).
