The Volgian-Valanginian succession of shallow-water deposits from the Olenek section ( Anabar-Lena region, Arctic Siberia) has been studied by sedimentological and palaeontological methods. High-resolution biostratigraphy of studied interval is based on the ammonites, foraminifers, marine and terrestrial palynomorphs. Foraminiferal and palynological zones have important regional implications providing well-constrained biostratigraphy of the Anabar-Lena region. Sedimentological studies together with ecological analysis of the associations of microbenthos, microphytoplankton and terrestrial palynomorphs allow the palaeoenvironmental reconstructions for the marginal area of the Anabar-Lena palaeosea and coastal land areas.
