Also known as Amoneburg
Where: Rhineland-Palatinate, Germany (50.0° N, 8.3° E: paleocoordinates 50.1° N, 6.2° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Wiesbaden Formation, MN 2 (22.4 - 20.0 Ma)
• "The Formation [i.e. the Wiesbaden Formation, formerly referred to as the Lower Hydrobia beds; TL] can be divided into three parts. The lower (brackish) and middle (lacustrine) parts are middle Aquitanian, containing the MN 2 mammal zone (Tobien 1988; Gers & Medden 1991; Reichenbacher 2000; Reichenbacher & Keller 2002). Reichenbacher (2000) assumed that the MN 2b and MN 3a mammal sub-zones of the Late Aquitanian–Early Burdigalian interval corresponded to the upper part of the Wiesbaden Formation, named the ‘emerging facies’. The squamate microvertebrate material described here was collected by Thomas Keller and colleagues from the lower brackish part of the Wiesbaden Formation where numerous freshwater and terrestrial gastropods, including Gyraulus, Stagnicola and Planorbarius, also occur." Age of the lower part of the Wiesbaden Fm is given as MN2a.
Environment/lithology: lagoonal or restricted shallow subtidal; limestone
Size class: mesofossils
Collected by Thomas Keller et al.; reposited in the SMF
Collection methods: sieve,
• "The fossils were recovered by screen washing and are housed in the SMF, prefixed by collection numbers of the PAL EV."
