Rudolfstollen waste heap, Seekopf Ridge, Lunz (Triassic of Austria)

Where: Austria (47.8° N, 15.0° E: paleocoordinates 13.1° N, 22.4° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Lunz Formation, Carnian (237.0 - 228.0 Ma)

• Collected from coal mine waste heap

• group of beds-level stratigraphic resolution

Environment/lithology: fluvial-deltaic; lithified, gray, silty shale

• Interpreted as deposits of a subaquatic delta that changed slowly to swampy coal-building environments, probably with sometimes brackish influence (Krystyn 1991). Several thin seams indicate frequently changing habitats caused by the meandering of the fluvial system. According to Sachsenhofer (1987), the coal is characterized by a remarkably high amount of cutinite (often with resinite) and almost complete lack of inertinite, which together with the high amount of siderite indicate that the coal was built in a gyttja environment.

Size class: macrofossils

Preservation: mold/impression, adpression
