Material: fragment of RV, embedded in rock (no. 24090- BBU-MPS).

Description: Right valve is conical with umbo curved ventrally, having 70 mm in length and 45/ 50 mm in diameter. The thickness of the outer shell layer varies between 3 to 4 mm. The ligamental ridge (L) is shorter, 7 mm in length, wider and clearly truncated ( Fig. 8j ). The first pillar (P1) is square and shorter than the second pillar (P2) which is slightly pedunculated at the base. In the specimen with right valve embedded in limestone the diameter in transverse section measure 35/ 45 mm, showing a ligamental ridge (L) strongly developed, triangular at the base and lamelliform, 13 mm in length, with inner termination truncated with V-shaped incision ( Fig. 8j ). The first pillar (P1) is thick, rectangular in shape, with sub-parallel flanks; shorter than L and P2, having 10 mm in length. The second pillar (P2) is slightly pinched at the base, 15 mm in length with a head oval-elongated and curved anteriorly. The compact outer shell layer is thin,

2-3 mm in thickness. No preserved myocardinal apparatus.

Observations: For many years species Vaccinites archiaci was assigned to Munier-Chalmas in the synonymy lists used by various authors. But, Vicens (1992) and Steuber (1999) draw attention that Douvillé (1892) described and illustrated this species for the first time based on the material from Munier-Chalmas which only mentioned ” Hippurites archiaci ” in his work, without description. So, correct attribution is Vaccinites archiaci Douvillé, 1892 .

Age and distribution: Santonian-early Campanian in Croatia ( Polšak and Mamuzic, 1969), Greece ( Steuber, 1999), Romania ( Lupu, 1976), early Campanian in France ( Astre, 1954; Bilotte, 1985), middle Campanian in southern Pyrenees ( Vicens, 1992); Campanian- Maastricthian in Afghanistan ( Vogel, 1971), BosniaHerzegovina (Sliskovic, 1984); Slovenia ( Pleničar and Sribar, 1992).
