Krustetten/Tiefenfucha [Ebelsberg Formation] (Oligocene of Austria)

Where: Austria (48.4° N, 15.7° E: paleocoordinates 46.4° N, 14.5° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Ebelsberg Formation, Chattian (28.1 - 23.0 Ma)

• STRATIGRAPHY: From the Ebelsberg Formation, which interfingers the Linz and Melk formations. AGE: Dated into the late Pollen Biozone Ng. Z. 1., Nannoplankton biozone NP 25, and planktic Foraminifera biozone P 22, and hence a Middle to Late Oligocene, or Early Egerian age, is inferred for the Ebelsberg Formation. Assigned here to the Chattian. STRATIGRAPHIC POSITION: From layer 9 of Roetzel (1983).

• bed-level stratigraphic resolution

Environment/lithology: offshore; lithified, concretionary, gray, blue mudstone

• ENVIRONMENT: Appears to be somewhat offshore, siliciclastic setting.
• SPECIFIC LITHOLOGY: Greyish and dark-blue pelitic sediments with scattered concretions, that contain most fossil material. LITHIFICATION: Lithified, on the basis of preservation.

Size class: macrofossils

Preservation: cast, mold/impression, concretion

Reposited in the NHMW

Collection methods: surface (in situ),

• COLLECTORS: Not stated. REPOSITORY: Inst. of Pal. Vienna, Geol. Surv. Austria Vienna, and Mus. Nat. Hist. Vienna.
