Where: Saxony-Anhalt, Germany (52.3° N, 11.1° E: paleocoordinates 46.5° N, 8.0° E)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: Selandian (61.6 - 59.2 Ma)
• "?upper Middle Paleocene (?MP 5, BiochroM'97, 1997)" = ? Selandian
•thought by Gingerich (1976) on the basis of Plesiadapis walbeckensis to be "correlated somewhere between the Ples. anceps and Ples. rex zones" (i.e., middle Tiffanian)
• group of beds-level stratigraphic resolution
Environment/lithology: fissure fill; unlithified, calcareous sandstone and unlithified, calcareous mudstone
Size class: macrofossils
Collection methods: The fissure was discovered in 1939. Subsequently it has completeley been mined out. Screenwashing of 16.5 m3 (33 t) of sediment revealed about 10,000 specimens (Bachmann, 2008). Most specimens are in the Geiseltal Museum in Halle, but some are in the BMNH (Gingerich 1976).
