Where: Lower Austria, Austria (48.2° N, 15.2° E: paleocoordinates 46.2° N, 14.0° E)
• coordinate stated in text
• outcrop-level geographic resolution
When: Pielach Formation, Chattian (28.1 - 23.0 Ma)
• STRATIGRAPHY: The section starts with about 1 m blueish to brown clay and silt with rootled beds. A rich macrofossil assemblage appears at the top of the overlying silty/sandy part of about 2 m thickness. Up to 1 m silty sand follows, with abundant gastropods. AGE: The Pielach Formation can be dated o the lower Polle Bozone Ng. Z. 1., ranging from the Kiscellian to the Early Egerian. The Early Egerian age can be inferred for the upper part of the Pielach Formation, based on its interfingering with the Melk and Linz Formations. Assigned here to Late Kiscellian-Early Egerian = Chattian.
• group of beds-level stratigraphic resolution
Environment/lithology: lagoonal; lithified, shelly/skeletal, silty sandstone
Size class: macrofossils
Collection methods: quarrying,
• Lists obtained from previous accounts and material obtained from collections at Inst. of Pal. Vienna, Geol. Surv. Austria Vienna, and Mus. Nat. Hist. Vienna. Further sources for this material is limited because hardly any contemporaneous outcrop exist beside the stream-bed at Kendl.
