Zumaya section, U3, Samples Z6, Thickness 18.20 m (Eocene of Spain)

Where: Spain (43.3° N, 2.3° W: paleocoordinates 38.7° N, 3.6° W)

• coordinate stated in text

• outcrop-level geographic resolution

When: Morozovella velascoensis zone, Ypresian (56.0 - 47.8 Ma)

• Lower Ypresian. Acarinina berggreni biozone.

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal; gray marl

• Unit U3 (40 cm) consists of grey marls. At the base of this unit (Z5), planktonic and benthic foraminifers are abundant and well preserved. Towards the top of unit U3 (Z6 and Z7), foraminiferal abundance and species richness decrease, and autochthonous foraminiferal calcareous tests are badly preserved and show partial dissolution.
• gray marls

Size class: mesofossils
