Where: Bolzano, Italy (46.3° N, 11.4° E: paleocoordinates 4.1° N, 25.7° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Val Gardena Formation, Zechstein (259.0 - 252.3 Ma)
• Palynological information supports a Thuringian age.
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial; micaceous, gray sandstone and micaceous, gray siltstone
• The sequence represents an alluvial-plain facies
• The Val Gardena Fm consists of well-bedded sandstones of variable grains, often micaceous, grading into fine siltstones and argillites or, locally, into conglomerates. The colour is generally red or reddisch; grey or green intercalations, may, however be frequently observed. Also lenses or beds of gypsum frequently occur. Locally rare calcareous interbeds are present. In the Dolomites and and the Vicentian Alps cross-bedded sandy and silty lithologies dominate. The sequence represents an alluvial-plain facies. Throughout the areal extent of the Val Gardena Formation grey interbeds may sometimes be rich in plant fragments of variable size and preservation. The deposits consist of sandstones of variable grains, often grading into fine siltstones.
