“…An ammonite-belemnite zonation proposed by Błaszkiewicz (1980), described from the Campanian and Maastrichtian of the Middle Vistula River, has never been used for the studied sequence. Recently, the inoceramid zonation of the Santonian and Campanian of the Miechów Synclinorium was published by Walaszczyk (1992), Jagt et al (2004), Jurkowska et al (2015), ammonite zonation by Machalski et al (2004), and foraminiferal biostratigraphy by Dubicka (2015). The authors correlate the biostratigraphical zonations with the belemnites/echinoids zonation described from North Germany (Schulz et al 1984) (Text- fig.…”

Dynamic evolution of the Campanian and Maastrichtian (Upper Cretaceous) of the Miechow Synclinorium is presented. Through chronostratigraphic analysis, the geometry of the Campanian and Maastrichtian of the area is interpreted, while microfacies analysis allowed determination of some of the paleoenvironmental parameters (rate of sedimentation, bottom condition and terrigenous input). The chronostratigraphy is based on inoceramid biostratigraphy. Nine inoceramid zones are recognized: Sphenoceramus patootensiformis, Sphaeroceramus sarumensis-Cataceramus dariensis and ‘Inoceramus’ azerbaydjanensis-‘Inoceramus’ vorhelmensis, ‘Inoceramus’ tenuilineatus, Sphaeroceramus pertenuiformis, ‘Inoceramus’ inkermanensis and ‘Inoceramus’ costaecus- ‘Inoceramus’ redbirdensis (Campanian); Endocostea typica and Trochoceramus radiosus (Maastrichtian). Five unconformities (isochronous in the study area) represented by horizons of slower sedimentation rate, were recognized. They correlate with eustatic sea-level changes, well recorded in European successions (Jarvis et al. 2002, 2006; Niebuhr et al. 2011). Unconformity horizons allow six alloformations to be distinguished. The thickness of particular chronostratigraphic units within the Campanian and Lower Maastrichtian increases progressively toward the axis of the Danish-Polish Trough, which indicates that the inversion of the trough could not have started before the Late Maastrichtian.

“…0.1-0.2 mm in diameter), one specimen is perforated (bored). The minchinellid species P. globularis is well known from the Upper Cretaceous of the Boreal Realm (Nestler 1961;Wood 2002;Neumann et al 2008;Wilmsen et al 2012;Jurkowska et al 2015). Commonly, a quiet and fairly deep-water environment is inferred as the habitat of the sponges that may have been anchored to the substrate by a non-calcified dermal tissue.…”

The benthic macroinvertebrates of the Lower Maastrichtian chalk of Saturn quarry at Kronsmoor (northern Germany) have been studied taxonomically based on more than 1,000 specimens. Two successive benthic macrofossil assemblages were recognised: the lower interval in the upper part of the Kronsmoor Formation (Belemnella obtusaZone) is characterized by low abundances of macroinvertebrates while the upper interval in the uppermost Kronsmoor and lowermost Hemmoor formations (lower to middleBelemnella sumensisZone) shows a high macroinvertebrate abundance (eight times more than in theB. obtusaZone) and a conspicuous dominance of brachiopods. The palaeoecological analysis of these two assemblages indicates the presence of eight different guilds, of which epifaunal suspension feeders (fixo-sessile and libero-sessile guilds), comprising approximately half of the trophic nucleus of the lower interval, increased to a dominant 86% in the upper interval, including a considerable proportion of rhynchonelliform brachiopods. It is tempting to relate this shift from the lower to the upper interval to an increase in nutrient supply and/or a shallowing of the depositional environment but further data including geochemical proxies are needed to fully understand the macrofossil distribution patterns in the Lower Maastrichtian of Kronsmoor.
