Boutersem TGV (Oligocene of Belgium)

Where: Brabant, Belgium (50.8° N, 4.8° E: paleocoordinates 50.2° N, 1.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Boutersem Member (Borgloon Formation), MP 21 (33.9 - 28.4 Ma)

• "at the base of" the member in a bed that "thickens up to 30 cm and consists of four layers"

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-lacustrine; shelly/skeletal, green, argillaceous sandstone

• the member is "a fluvio-lacustrine complex" and the avifauna indicates "an aquatic paleoenvironment" with an "absence of forests in the close vicinity"
• the four layers are "a pinkish shell-bed, often indurated (5 to 10 cm), greenish clayey sands with crushed, partially decalcified shells (5 to 10 cm), a dark-green clay without shells (2 to 3 cm) and greenish shelly sands with reddish discontinuous bands (10 to 15 cm)"

Size classes: macrofossils, mesofossils

Collected in 1999

Collection methods: bulk, salvage, sieve,

• "screen washed"

•material is in the Institut Royal des Sciences Naturelles de Bruxelles, Belgium (IRScNB)
