This paper describes and interpretes a Sarmatian palaeoflora identified within Şupanu Formation. This
formation was intercepted in 2 outcrops: one located in Asău cuvette and the other one in Lăloaia-Galeon cuvette.
Based on palaeofloristic investigations a palaeoenvironmental and palaeoclimatical reconstruction was accomplished. In
the Sarmatian, Comăneşti Basin recorded an abundant plants biomass development, in a swamp environment, allowing
coal layer formation. The TAXODIACEAE have been the main source in coal formation, plus some taxa such as Typha and
Phragmites. Additionaly, was also identified a lowland riparian vegetation and other taxas from a mixed mesophytic
forest. Palaeoclimatical values were estimated by the “Coexistence approach” method. This paper present also
palynofacies analysis on basis of the organic matter extracted from analyzed samples. It was observed that organic
matter is almost entirely derived from the continent (black coal phytoclasts, brown and yellow residues, woody tissues,
spores and pollen).
