Petresti-Arini section, Sebes locality (Cretaceous of Romania)

Also known as Petreşti-Arini

Where: Romania (45.9° N, 23.6° E: paleocoordinates 36.4° N, 22.0° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Bozeş Formation, Late/Upper Campanian (83.5 - 70.6 Ma)

• CC22 biozone, corresponding to the lower-mid upper Campanian.

•The uppermost interval of the Bozes Formation

Environment/lithology: offshore; sandstone and marl

• alternating sandstones and marls/clays deposited in turbiditic facies. In the uppermost part of the marine succession, immediately below the transition to the Cerithium-bearing dark gray marly siltstones and mudstones, vegetal detritus begins to appear in certain sandstone beds, suggesting terrestrial influx. Together with the decreasing abundance of calcareous nannofossils, this build up of vegetation suggests a gradual up-section shallowing of the depositional environment.
• claystone/siltstone and fine sandstone

Size classes: macrofossils, mesofossils
