Geinitzia reichenbachii is the most common species. Dryophyllum westerhausianum (Richter, 1904) Halamski and Kvaček comb. nov. is a trifoliolate leaf re-interpreted as a representative of Fagales. Three species of Dewalquea are distinguished: Dewalquea haldemiana, Dewalquea insignis , and Dewalquea aff. gelindenensis. Platanites willigeri Halamski and Kvaček sp. nov. is characterised by trifoliolate leaves, the median leaflet of which is ovate, unlobed, with a serrate margin, and cuneate base. Palaeocommunities inferred from the megafossil record include: a back swamp forest dominated by Geinitzia, with abundant ferns; a Dryophyllum-dominated riparian forest; a forest with Dewalquea and Platanites willigeri possibly located in the marginal part of the alluvial plain; dunes with D. haldemiana and Konijnenburgia; a fern savanna with patches of Pinus woodlands. Palynoassemblage A from the Nowogrodziec Member, studied mostly at Rakowice Małe and Żeliszów, consists of 126 taxa, including 105 terrestrial palynomorphs (54 bryophyte, lycophyte, and pteridophyte spores, 16 gymnosperms, 35 angiosperms). The mega-and mesofossil records are dominated by angiosperms; the palynoassemblages are dominated by ferns. Palaeocommunities represented solely by the microfossil record are halophytic (with Frenelopsis and unconfirmed presence of Nypa) and pioneer vegetation. Palaeocommunities are intermediate in general character between those pre-dating the Cretaceous Terrestrial Revolution and modern, angiosperm-dominated vegetation. In comparison to older plant assemblages from contiguous areas laurophylls are much rarer; this might correspond to a real phenomenon of exclusion of lauroids from Santonian riparian forests. The studied assemblage is more similar to younger palaeofloras than to older ones; this might be interpreted as stabilisation of communities after a period of pronounced change related to the rise to dominance of the angiosperms. In contrast to widespread endemism among vertebrates of the European Archipelago, the plant cover consists mostly of species that are widely distributed.
Five sedimentation episodes ranging from Upper Cenomanian to Lower Turonian (Korycany Member of the Peruc-Korycany Formation and Bílá Hora Formation) are documented from new outcrops at the Chrtníky quarry, Bohemian Cretaceous Basin (BCB). The first episode belongs to the lower <i>Metoicoceras geslinianum </i>Zone and is recorded only as phosphatic intraclasts in younger beds. The second and third episodes (upper <i>M. geslinianum </i>Zone) are represented by coarse conglomerates separated by an interval of condensed sedimentation, phosphogenesis, and erosion of incompletely lithified deposits. The third sedimentation episode is cut by erosion. Probably after a stratigraphic gap, a fourth episode followed and included further shaping of the underlying erosion surface (formation of a hardground s. lat.), stromatolite growth and phosphogenesis (second interval of condensed sedimentation), corrosion and redeposition of diabase clasts, calcareous mud deposition and firmground formation, and, finally, deposition of dark claystone and burrowing. This succession seems to be of Early Turonian age, <i>Whiteinella archaeocretacea </i>(?) Zone. Basal portions of the fifth sedimentation episode (Lower Turonian, <i>Helvetoglobotruncana helvetica </i>Zone) started after the erosion event and included marly deposits rich in macrofauna, whereas the overlying strata yield an impoverished fauna predominated by sponges. In the topmost part of the succession, fully oxic conditions with abundant macrofauna are documented. The biostratigraphic conclusions are based on macrofauna and micropalaeontology (palynomorphs and foraminifera), and on correlations with other shallow-water successions (Předboj, Velim, Pecínov). Finds of enormously abundant remains of the crinoid <i>Cyathidium </i>aff. <i>depressum </i>(Sieverts) are unique. Common bryozoan and microfossil associations document a deepening of the basin during the fifth sedimentation episode. An identical development is documented by gradual changes in ecologic types of sponges (<i>Pachytilodia bohemica</i> rarr;<i>Chonella</i>-<i>Verruculina</i>-<i>Siphonia</i> rarr;<i>Laocoetis</i>-<i>Guettardiscyphia-Diplodictyon </i>assemblages). The taphonomy of macrofauna supports previous views of the geological and sedimentological developments in the area. Nontronite, which causes the greenish colour of clay laminae mainly in stromatolites, was identified for the first time in the BCB
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
