FIGURE 17. Kogaionid-bearing fossiliferous localities from the Rusca Montană (A) and southwestern Transylvanian (B–F) basins. A. Exposures of uppermost Cretaceous continental beds along Fărcădeana Creek at Negoiu, Lunca Cernii de Sus, eastern Rusca Montană Basin. Hammer marks the position of the fossilfierous bed hosting site RM1. B. Overview of the Oarda de Jos A locality, south of Alba Iulia, on the right side of Sebeș River (in the foreground). The fossiliferous bed hosting site TB1 is located in the upper part of the outcropping succession. C. Strongly tilted beds of the continental Sebeș Formation outcropping at PetreștiArini, covered by flat-lying Quaternary sandy-pebbly deposits and recently created anthropic sediment heaps. D. Red mudstone-dominated part of the basal section of the Sebeș Formation at Petrești-Arini, hosting site TB2. E. Outcrops of the Sebeș Formation at Sebeș-Glod, along the Sebeș River, locality Sebeș-Glod A, with kogaionid site TB3 near the group of people to the left. F. The transitional sequence from the estuarinebrackish uppermost Bozeș Formation (right) to the continental, gray-colored basalmost Sebeș Formation (left, more ochre-colored rocks) at Petrești-Arini, hosting the Black Lens fossiliferous level (site TB4).
