Adnet Grosser Langmoos Quarry 2b (Jurassic to of Austria)

Also known as Quarry XVII 2b

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: Angulaticeras marmoreum ammonoid zone, Guggen Member (Schnoll Formation), Middle Hettangian to Middle Hettangian (201.4 - 199.5 Ma)

• Limestone bed 2b (co-called Enzesfeld Limestone) forms uppermost part of the Guggen Member an it is capped by ferruginous Marmorea crust

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified, condensed, ferruginous, glauconitic, shelly/skeletal packstone

• Sediment starvation may have been caused by current activity combined with strongly reduced input of carbonate mud due to the widespread drowning during the Middle Hettangian
• Red glauconitic condensed facies.

•Microfacies: echinoderm-foram biomicrite with gastropods (wacke- to packstone). Intercalated hardgrounds may consist of brownish-yellow phosphatic sediment or of dark Fe/Mn oxides.

Size class: macrofossils

Preservation: mold/impression, original calcite, replaced with calcite

Collection methods: bulk, mechanical,
