Adnet Lienbacher Quarry (Jurassic to of Austria)

Also known as Quarry XII

Where: Austria (47.0° N, 13.0° E: paleocoordinates 32.2° N, 17.2° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Angulaticeras marmoreum zone, Guggen Member (Schnoll Formation), Middle Hettangian to Middle Hettangian (201.3 - 196.5 Ma)

• 0-10 cm thick red crinoidal limestone with brachiopods overlies the Rhaetian limestone and it is capped by the ferromanganese "Marmorea Crust", .

• bed-level stratigraphic resolution

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

• Hettangian sediments represent post-drowning sequences on the steep constructional morphology of the Rhaetian reef. According to microfacies analysis it is supposed that deposition took place in cool deeper water, below a pycnocline. Sediment starvation may have been caused by current activity combined with strongly reduced input of carbonate mud due to widespread drowning in the Middle Hettangian.
• 0-10 cm thick red condensed limestone, rich in brachiopods.

•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,
