Název v původním jazyce

Bioturbation of claystones of the Most Basin in the Bílina Quarry (Miocene, Czech Republic)

Popis výsledku v původním jazyce

In the Miocene of the Most Basin, tuffitic substrates underlying the Main Coal Seam yielded the trace fossil Taenidium isp. The body of lacustrine clays above the Main Coal Seam contains frequent ?Selenichnites isp. The persistent horizon of dark clay provided finds of Unisulcus. A substantial part of the mudstone deposits of the Bílina delta shows a well-visible, intensive bioturbation by Planolites montanus. Finds of Taenidium isp. point to the settings of periodically inundated paleosols. ?Selenichnites isp. occurs in quiet, shallow-water lacustrine settings. The same regime could be characteristic for Unisulcus-dominated sediment, with perhaps stronger ecological stress for most of the benthic fauna. The Planolites montanus assemblage had been cyclically suppressed by rapid sedimentation and subsequent biological influence. It is likely that the periodicity of the cycle was very short, probably annual.
