Abstract (in english)
   The succession of the Peruc and Korycany Members in the Pecínov quarry, Bohemia, reflects the interplay of 4th-order sea-level fluctuations, of approximately 100-120 ka periodicity, and a long-term (3rd-order) sea level rise of the late middle through early late Cenomanian. The succession studied includes deposits of a shallow, gravelly braided river (unit 1), tide-influenced braided river (unit 2), supratidal marsh (unit 3), tidal flat (unit 4) and ebb-tidal delta to estuary mouth fill (unit 5). Units 1-5 are interpreted as parasequences of a single depositional sequence, units 1-4 together make up a transgressive systems tract and unit 5 is a highstand deposit, capped by a sequence boundary. The presence of deciduous plants attests to a certain degree of seasonality of the climate.
   The mixing of thermophile and temperature vegetation, together with the presumed palaeolatitudinal position of the Bohemian Massif, suggests a generally slightly semi-arid (i.e., seasonally wet) regional climatic conditions during the deposition of units 1-5; substrates in local habitats in alluvial valleys and estuary margins were damp due to high local water table
