High-frequency sea-level fluctuations and plant habitats in Cenomanian fluvial to estuarine succession: Pecínov quarry, Bohemia

Fossil calibration of Magnoliidae, an ancient lineage of angiosperms

“…in the lower Raritan Formation of New Jersey (Zone IV) and the upper part of the Peruc Formation of Bohemia (Pacltová, 1971;Doyle and Robbins, 1977), and by late Cenomanian ammonites in the lower Raritan (Cobban and Kennedy, 1990). The Peruc Formation underlies marine sediments with late Cenomanian mollusks, and its upper part was correlated palynologically by Pacltová (1977) with late middle Cenomanian marine beds that contain the first Normapolles in England and France (Azéma et al, 1972;Laing, 1975); this agrees with studies of sequence stratigraphy in the Bohemian section by Uličný et al (1997). The probable latest Albian age of Potomac Subzone II-C is discussed under Virginanthus.…”

Late Cretaceous (Campanian) leaf and palynoflora from southern Skåne, Sweden

“…Although Perinopollenites might be affiliated with the relatively abundant Pagiophyllum, the producers of the Classopollis grains are uncertain. Classopollis derives from cheirolepidiacean conifers, particularly Frenelopsis, which typically occurs in Late Cretaceous marine-influenced habitats (Uličný et al 1997). This type of conifer is characteristic of Late Cretaceous halophytic habitats (Uličný et al 1997;Kvaček 2000).…”

Carbon and oxygen stable isotopes of selected Cenomanian and Turonian rudists from Egypt and Czech Republic, and a note on changes in rudist diversity

“…The sedimentation of Cretaceous deposits in the BCB started in the Early and continued during the Middle Cenomanian as a typical continental depositional sequence (Peruc Beds of the local stratigraphic column; Malkovský et al 1974;Čech et al 1980;Uličný et al 1993Uličný et al , 1997. The basal sediments reflect fluvial freshwater sedimentation with very coarse material deposited by rivers.…”
