Andrès (MNHN-UL) (Jurassic to of Portugal)

Where: Estremdura, Portugal (39.9° N, 8.6° W: paleocoordinates 33.8° N, 2.1° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Alcobaça Formation, Late/Upper Oxfordian to Late/Upper Oxfordian (161.2 - 150.8 Ma)

• = Camadas de Alcobaça, could also be from lowermost Bombarral Formation (= Grès superiores); Malafaia et al 2010 consider the site to be ?upper Kimmeridgian to Tithonian in age

• bed-level stratigraphic resolution

Environment/lithology: fluvial; paleosol/pedogenic, micaceous, gray, carbonaceous sandstone and fine-grained siltstone

• "deposited in a fluvial meandering environment with subsidiary deltaic and marginal marine environments.", also called a shallow, distal river setting
• "mainly represented by micaceous sandstones (as occur in Andrès), fine sands and silts", also described as "sandstones and marls that represent paleosols", also described as "fine-grained mud-sandstones, sometimes micaceous, with intercalations of some levels of marls, silts and clays, sometimes with

•abundant calcareous or limonitic nodules"

Size classes: macrofossils, mesofossils
