Where: Thuringia, Germany (50.8° N, 10.6° E: paleocoordinates 8.9° N, 22.6° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Tambach-Sandstein Member (Tambach Formation), Artinskian (290.1 - 279.3 Ma)
• "At the Bromacker quarry site are two superimposed stratigraphic successions that can be characterized by their facies associations and are referred to as the Lower Beds and Upper Beds (Eberth et al. 2000). All the vertebrates from the Bromacker quarry come from the Upper Beds [...]. The vertebrates are almost exclusively restricted to two [... horizons ...] which are separated by 50 cm in a stratigraphic interval of 1.2 m." (Berman et al., 2001)
•The Tambach Formation is of Artinskian age according to "Stratigraphische Tabelle von Deutschland 2002", however, a Kungurian age is proposed by Lützner (2006) in LITHOLEX stratigraphic online database [http://www.bgr.de/app/LithoLex/gesamt_ausgabe_neu.php5?id=25]
• group of beds-level stratigraphic resolution
Environment/lithology: fluvial-lacustrine; lithified, brown, red sandstone
•"During the time that the Lower and Upper beds were deposited, the Tambach Basin was internally-drained and probably characterized by a wet-and-dry tropical or wetter climate that was hot year-round with seasonal-to-subseasonal cycles of rainfall and drying. [...] In the Bromacker area, the floodbasin was never deeply desiccated or heavily vegetated between flooding events." Eberth et al. (2000).
