Abstract

A palynological study carried out at the Pliensbachian-Toarcian passage beds of the Rambla del Salto section (Teruel province, E. Spain) has led to the identification of twenty-one taxa belonging to sorne different groups of Protoctista, gymnospenn and vascular criptogamme plants. The identified taxa show a wide stratigraphic range and have low biostratigraphic value. Two separate intervals are distinguished by their content in planktic elements. In both intervals palynologic associations are difficult to compare with other european basins. Recorded planktic taxa disappear at the Miiabile-Semicelatum Subzone transition (lower Toarcian). This might be related with the suboxie events which has been recognised elsewhere in some other areas in the basin.
