Garschella Fm - Bezeck near Bezau, Vorarlberg (Cretaceous of Austria)

Where: Austria (47.4° N, 9.9° E: paleocoordinates 31.4° N, 19.7° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

When: Garschella Formation, Aptian (125.0 - 113.0 Ma)

• LITHOSTRATIGRAPHY: From the Garschella Formation, which represents the "Gault" of Zittel 1868, Vacek 1879, and Föllmi and Ouwehand. The Garschella Fm overlies the Schrattenkalk, Drusberg, and Mittagspitz Fm, and is overlain by the Seewer Kalk Fm. AGE: Aptian in age, although justification for age assignment not provided.

• group of beds-level stratigraphic resolution

Environment/lithology: lithified, shelly/skeletal limestone

• ENVIRONMENT: Considered to be boreal or temperate. Abundance of ammonites suggests environments that were bathymetrically deeper than those of nerineaceans, anthozoans, etc.
• SPECIFIC LITHOLOGY: Condensated and highly fossiliferous, lithified (as many specimens are internal moulds). Presumably from chalk facies. LITHIFICATION: Lithified based on facies description and taphonomic comments.

Size class: macrofossils

Preservation: mold/impression

Reposited in the MNHN

Collection methods: surface (float),

• COLLECTORS: H.A. Kollmann and historic authors (notably Vacek, 1879, Baumberger and Fussenegger, 1933, and Heim et al. 1934). REPOSITORY: Collections reposited in the Vorarlberger Naturschau, Geologische Bundesantalt, Bayerische Staatssammulung fur Geologie und Palaontologie, Hungarian Geological Survey, and Museum National d'Historie Naturelle, Paris.
