The aim of this work is to present some diverse and well-preserved larger foraminiferal assemblages from Thanetian (SBZ 3; Serra-Kiel et al., 1998) deposits from central-southern Zakynthos (Ionian Islands). The investigated assemblages originate from a heterometric conglomerate of uncertain age (Oligocene-Miocene?), disconformably overlying well-bedded Upper Cretaceous pelagic limestone, cropping out along the Macherado/Romiri-Agalas road, near the village of Kiliomeno. Clasts yielding SBZ 3 assemblages largely prevail. Besides well-known index taxa such as Coskinon rajkae (Hottinger & Drobne, 1980), Fallotella alavensis Mangin, 1954, Vania anatolica Sirel & Gündüz, 1985 and Glomalveolina primaeva primaeva (Reichel, 1936), these clasts yield some rare or unrecorded forms, mostly with porcelaneous test. The unusual occurrence of several well recognizable specimens of Glomalveolina primaeva ludwigi (Reichel, 1936) is recorded. Biometrical data for some taxa (including small-sized Glomalveolina specimens) are given.

Abstract
The aim of this work is to present some diverse and well-preserved larger foraminiferal assemblages from Thanetian (SBZ 3; Serra-Kiel et al., 1998) deposits from central-southern Zakynthos (Ionian Islands). The investigated assemblages originate from a heterometric conglomerate of uncertain age (Oligocene-Miocene?), disconformably overlying well-bedded Upper Cretaceous pelagic limestone, cropping out along the Macherado/Romiri-Agalas road, near the village of Kiliomeno. Clasts yielding SBZ 3 assemblages largely prevail. Besides well-known index taxa such as Coskinon rajkae (Hottinger & Drobne, 1980), Fallotella alavensis Mangin, 1954, Vania anatolica Sirel & Gündüz, 1985 and Glomalveolina primaeva primaeva (Reichel, 1936), these clasts yield some rare or unrecorded forms, mostly with porcelaneous test. The unusual occurrence of several well recognizable specimens of Glomalveolina primaeva ludwigi (Reichel, 1936) is recorded. Biometrical data for some taxa (including small-sized Glomalveolina specimens) are given.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
