Abstract (in english)
   A study of the Late Cretaceous rocky coast deposits of the Unhošť-Tursko High lying west-northeast of Prague is undertaken here. Based on the record of the rocky bottom characters, overlying sediments, phosphates, distribution of foraminifers, palynomorphs and macrofaunal taphocoenoses, two sedimentary setting each with its own phosphogenesis have been distinguished. The phosphogenic products are in part reworked and redeposited into younger beds. The older phosphatic remains are reported from the conglomerate in which the taphocoenose with Gisilina? rudolphi and Goniopygus cf. menardi occurs. Part of the two sections (Předboj and Černovičky) characterized by this taphocoenose belong to the upper part of Metoicoceras geslinianum Zone and are discussed here in more detail. The younger phospogenic episode is probably of the early Turoanian age.
   Both the proper phospogenic episodes and subsequent development of strata are correlated with the updip succession of the Pecínov Member and the Bílá Hora Formation in the Pecínov quarry. The palaeoenvironments of principal intervals are briefly discussed to elucidate problems of phospogenesis and distribution of faunal remains
