Portugal E8/58 (Jurassic to of Portugal)

Where: Portugal (39.1° N, 9.3° W: paleocoordinates 33.4° N, 1.0° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Lourinhã Formation, Late/Upper Kimmeridgian to Late/Upper Kimmeridgian (155.7 - 145.0 Ma)

• Taylor et al. 2013: Underlying Abadia Formation sediments have a similar biostratigraphical signature to the Porto de Barças Member and both contain shell beds with abundant Isognomon lusitanicum, Praeexogyra pustulosa and Nanogyra nana. Both the Abadia Formation and the Porto de Barças Member are biostratigraphically dated as Late Kimmeridgian. The Porto de Barças Member was replaced by the Praia Azul member according to Mateus et al. 2017 which is latest Kimmeridgian–earliest Tithonian.

Environment/lithology: offshore; muddy claystone and marl

• marly clay (upper part: marly silt, no fauna), offshore shallow shelf; sample from the base

Size class: macrofossils

Preservation: replaced with calcite

Collection methods: bulk, mechanical,
