Stratigraphy comments: STRATIGRAPHIC RELATIONS: From the Bilá Fm, which overlies the Korycany Mbr of the Peruc-Korycany Fm. AGE: Early Turonian, presumably on the basis of foraminiferal and macrofossils biostratigraphy. STRATIGRAPHIC POSITION: From a deep depression, named the Giant Channel, situated in the eastern part of the quarry. Collection is from near top of section, Unit 8f (clayey siltstone with diverse macrofauna), which is about 1-1.4 m thick.
