Baer knolls (BK) are elongated ridge and depressions often close to the sub-latitudinal orientation sometimes spatially isometric that are widespread in the entire Northern Caspian Region up to 0 m a.s.l. that is the upper limit of the Late Khvalynian sea transgression. We identify it as giant dunes, formed under water in subcritical regime of the flux. Studying these landforms is very important for restoring the history of the Caspian Sea and environments that existed on its shores during the Late Pleistocene - onset of Holocene. The results of radiocarbon dating of mollusk shells based on four samples showed the age from 16.4 to 13.8 th years cal mostly correlating with the period of deglaciation after LGM.
