Description	Svrchnoturonské sedimenty, převážně jílovité krabonáty, byly na lokalitě Úpohlavy (Severní Čechy)kolonizovány in-faunou podle vzorců do značné míry závislých na postupném zpevňování dna (softground - stiffground - firmground), což lze zobecnit i v případě jiných %22klastických karbonátů%22 nebo krabonátů s velkou příměsí klastického materiálu (např. ordovik petrohradské oblasti). (cs) Basal beds of the Upper Turonian sediments at the Úpohlavy Quarry, corresponding to clayey limestone in its character, bears obvious signs of rapid lithification from softground to firmground (Ophiomorpha – Thalassinoides – Spongeliomorpha). Immediately before reaching the firmground stage, the substrate was colonized by tracemakers of chemichnia (Chondrites). Biogenic reworking of the overlying, irregularly rhythmically bedded limestone/marlstone beds does not fit the idea that the differences between the limestone and marlstone ichnofabrics are due to primary fluctuations in oxygen content in water and in sediments. Documentation of a section of approx. 10–13 m above the base of the succession revealed that bioturbation down to the depth of ca. 20 cm is more intensive in beds with higher calcium carbonate content (Thalassinoides often passively filled with clay-richer substance and subsequently colonized by Chondrites tracemakers).
