Paleontology

Fiorina DIACONU Geological setting From geological point of view, the studied area represents the westernmost side of the Dacian Basin and involves among other various lithologies, marl tuffite clay with numerous foraminifers, equivalent “marls with glohigerinae” from Muntenia (Marinescu, 1978). These Badenian deposits form a continuous band around Godeanu, on Topolnqei Valley to south, at Bala on Räienilor Valley. In this area, at Bälväne§ti, near the contact with the metamorphic rocks the Badenian is cropping out. It concerns clays and fossil-bearing sandy clays. Within the studied area, the Badenian sedimentary succession begins with the level of marls bearing glohigerinae and continues with marls, sands, sometimes interbedded with gravel -which contains the richest fauna- and tuffite or tuffitic clays. Locally, in the Balvane§ti sector, above them there is very fossil-bearing gravel, sand and marl clay. They also include a layer of volcanic tuffite. To the north, sands and marl clays reach big thickness, replacing the gravel. The Badenian deposits sequence exposed on the left bank of Neagonea Valley contains (fig.l): gravel with boulder (2 m), fossiliferous gravel (1.5 m), clay with tuffite lens (lm), coarse gravel mixed with boulders (4 m), sandy layers and blocks (5 m).

The findings are important because they originate from the sands and clay sands where they were preserved. The species were assigned based on measurements and morphology, than compared with the specimens described and figured in paleontological references.
