Where: Austria (47.4° N, 9.9° E: paleocoordinates 33.9° N, 19.7° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Gemsmättli Member (Kieselkalk Formation), Valanginian (139.8 - 132.9 Ma)

• LITHOSTRATIGRAPHY: From the Gemsmattli Mbr of the Kieselkalk Formation. AGE: Based on ammonite biostratigraphy the collection is assigned a stratigraphic range from Upper Valanginian (olcostphanids (radiatus zone)) to the basal Lower Hauterivian (Breistrofferia species). As from lower part of formation the collection is assigned to the Valanginian to avoid orphaning. STRATIGRAPHIC POSITION: From base of formation.
