cliffs south of Praia de Valmitão (VAL) (Jurassic of Portugal)

Where: Lourinha, Portugal (39.2° N, 9.3° W: paleocoordinates 33.5° N, 1.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Praia da Amoreira-Porto Novo Member (Lourinhã Formation), Late/Upper Kimmeridgian (155.7 - 150.8 Ma)

• upper half of member

• bed-level stratigraphic resolution

Environment/lithology: terrestrial; massive, tabular, paleosol/pedogenic, gray, silty mudstone and massive, fine-grained, medium, brown sandstone

• "an environment with low sediment supply and long periods of subaerial exposure"
• "a multicolored succession of greyish and purplish silty marls, violet and orange mudstones, being common interbedded brownish sandstones. Strata are dm in thickness and show a tabular geometry. The fine-grained lithologies show massive texture and frequently carbonate nodules, while in the mudstones rhizoliths, rhizotubules and mottling are also very common. The fine to medium sandstones comprise massive or cross-laminated strata with some rounded extraclats (< 2 cm in diameter)."

Size classes: macrofossils, mesofossils
