Szentpéterfalva, Hateg Basin (Cretaceous of Romania)

Also known as Sânpetru, Sînpetru, Sâmpetru, Sîmpetru, Sacel, La Carare, Sinpetru

Where: Hunedoara, Romania (45.6° N, 22.9° E: paleocoordinates 32.6° N, 21.1° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: lower Member (Sânpetru Formation), Early/Lower Maastrichtian (70.6 - 66.0 Ma)

• Ţabără and Slimani, 2019: The Sînpetru Formation was first assigned to the upper Maastrichtian on the basis of the presence of the pollen Pseudopapilopollis praesubhercynicus (see Antonescu et al., 1983). This assignment was later questioned by Van Itterbeeck et al. (2005), who suggested a lower/upper Maastrichtian boundary interval. Palaeomagnetic studies indicate that the Sînpetru Formation was laid down between the beginning of Chron 32n.1 and the end of Chron 31n (68.7–71.5 Ma) (Panaiotu and Panaiotu, 2010). The age of this formation is more difficult to establish due to its low content in palynomorphs and long-ranging taxa such as Deltoidospora minor, Gleicheniidites senonicus and Laevigatosporites ovatus. All taxa identified by us from the Sînpetru Formation were also previously recorded from the same deposits by Van Itterbeeck et al. (2005) and Csiki et al. (2008). Therefore, we agree the early/late Maastrichtian age of this formation, as suggested by Van Itterbeeck et al. (2005) on the basis of a more conclusive palynological content.
