Where: Czech Republic (50.0° N, 15.6° E: paleocoordinates 40.1° N, 14.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Bilá Formation, Early/Lower Turonian (93.5 - 89.3 Ma)
• 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 8a-e (siltstones with sponges), which is about 1.5-2 m thick.
• bed-level stratigraphic resolution
Environment/lithology: marine; poorly lithified, gray, yellow siltstone
Size class: macrofossils
Collected by Vodrazka & Zitt
Collection methods: bulk, surface (in situ),
