AL1-Jura (Cretaceous of Switzerland)

Also known as La Vraconne

Where: Switzerland (46.8° N, 6.5° E: paleocoordinates 35.4° N, 10.6° E)

When: Perte du Rhône Formation, Albian (113.0 - 100.5 Ma)

• The author describes the Albian as the Gault, which is divided into upper, middle and lower intervals. This is a general collection for the upper Albian. Strasser et al. 2016 proposed the three members belong to the Perte du Rhône Formation.

•Strasser et al. 2016: The uppermost early and early middle Albian is represented by marls, which are more developed in the Swiss part of the Jura Mountains (up to 30 m thick), and which contain pyritized ammonites (‘‘Albien pyriteux’’). The third, upper part of the formation is a mica- rich sandstone with variable amounts of glauconite. This unit is present only in the southern French Jura.

Environment/lithology: terrestrial; gray, yellow sandstone

• Jaccard, 1869: A Ste-Croix ce terrain présente une assisse puissante, irrégulièrement stratifée de grès marneux, jaunâtre ou verdâtre, dans laquelle les fossiles sont très-irrégulièrement repartis.

Size class: macrofossils
