Trace fossils from the Roblín Member of the Srbsko Formation (Middle Devonian, Barrandian area, central Bohemia)

Journal of the Czech Geological Society, volume 41 (1996), issue 1-2, 79 - 84

Trace fossils show that the Roblín event at the boundary between the Kačák Mbr. and the Roblín Mbr. (of the Srbsko Formation, Middle Devonian of the Barrandian area) is comparable to the regressive (glacioeustatic) event at the base of the Kosov Formation (Upper Ordovician of the Barrandian area): the ichnoassemblages formed mostly by Chondrites are substituted by a mixture of elements of the Arenicolites, Cruziana and Nereites Ichnofacies. The studied ichnoassemblage of the Roblín Member contains the ichnogenera?Arenicolites, Planolites, ?Chondrites, Gordia, Helminthopsis, Treptichnus, ?Urohelminthoida, Bifungites, and Zoophycos. The ichnoassemblage is consistent with the presumption that the sedimentation in the Prague Basin was terminated by the Roblín Member.
