   Faunal and floral fossil remains of Late Cretaceous - Early Palaeocene age were recovered from flint pebbles from glaciofluvial gravel sediments in the Fukov area, northern Bohemia, the Czech Republic. Sedimentology of these sediments is discussed. Suggestions are made regarding the origin of the flints and their possible sources. The recovered taphocoenosis consists of one fossil plant taxon, nineteen bryozoans, three molluscs, one sabellid, and seven echinoderms. This type of flint and fossil fauna may indicate a pioneer character of the association found in glaciofluvial sediments near Fukov, perhaps an unconsolidated environment on a continental shelf margin which is characteristic for North-western European chalk. The occurrence of plant fossil in this type of deep shelf sediment is unique and suggests the existence of some land mass at a relatively close distance to the place of deposition.
