Adnet Schnoll Quarry 5a (Jurassic of Austria)

Also known as Quarry XXXI (5a)

Where: Austria (47.0° N, 13.0° E)

• Paleocoordinates: 28.9° N, 30.1° E (Wright 2013)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Psiloceras calliphyllum ammonoid zone, Langmoos Member (Schnoll Formation), Early/Lower Hettangian (201.4 - 199.5 Ma)

• The Langmoos Member is only present in basal part in the left (northeastern) part of the quarry, where it is 1.5 m thick

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, shelly/skeletal, green, calcareous limestone

• At the boundary of Calliphyllum (Planorbis) and Liasicus Zone, late LST and transgresive system tract conditions are supposed. Onlap of the Schnoll Formation at the slope as a lowstand edge. Poorly oxygenated, nutrient-rich bottom waters fostered dense sponge populations.
• red, grey and greenish limestone bioclastic limestones with brachiopods, crinoids, sponge spicules

Size class: macrofossils

Preservation: original calcite

Collection methods: bulk, mechanical,
