Abstract: The Plana de Vic is located towards the NE of the Ebro Basin and is mainly characterized by a thick pile of marine sediments that accumulated along the Palaeogene. Overlying a Palaeozoic basement and a marked unconformity are fine-grained non-marine materials (Thanetian), which are covered by the accumulation of a thin marine wedge (Ilerdian). These marine materials were subsequently overlain by fine- and coarse-grained alluvial deposits. Towards the upper part of these alluvial deposits are sandstones and limestones with Nummulites and Assilina. Thereafter, lutitic materials deposited offshore were covered by the prograding coastal sandy materials. In the central part of the basin the accumulation of offshore lutites continued (Bartonian). These lutites were affected by the southwards and northwards deltaic progradations. Limestonedominated reefs were deposited over the deltaic bodies. On top of the sedimentary unconformity is a complex accumulation of lutites, sandstones, evaporites and limestones (Terminal complex) containing the remains of the fossilized fish (Priabonian). Some specimens of Clupeids, Percoformids and Synodonts represent the last episodes of the Eocene marine sedimentation in the study area. Key-words: Fossil fishes, Plana de Vic, Ebro Basin, Palaeogene, Priabonian.
