Unit 23 (Barremian) - Castagne (W of Bargeme) (Cretaceous of France)

Where: Provence, France (43.7° N, 6.6° E: paleocoordinates 34.0° N, 16.3° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Barremian (129.4 - 125.0 Ma)

• Collection from bed 23, 2.5-6 m thick limestone, from the upper Barremian. No apparent lithostratigraphic nomenclature.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, glauconitic, calcareous limestone

• No paleoenvironmental data readily apparent; obviously from a carbonate facies, however.
• Glauconitic lithified limestone (calcaires compacts, a cassure porcelanee et parine claire, legerement glauconieux ou non).

Size class: macrofossils

Collection methods: Collection a composite for the unit described in text.
