Abstract
Early Sarmatian bony fish assemblages from the Pshekha River (northern Caucasus) and the village of Naslavcea (northern Moldova) are compared. It is proposed that, in the Early Sarmatian, connection between the North Caucasian and Moldavian basins was hampered and the two fish localities were formed under different conditions. The impoverished taxonomic composition of Sarmatian fishes from the Eastern Paratethys is attributable to unfavorable chemical composition (increased alkalinity) rather than to low salinity.
