Where: Canton de Vaud, Switzerland (46.7° N, 6.5° E: paleocoordinates 44.7° N, 2.5° E)
• coordinate estimated from map
• small collection-level geographic resolution
When: MP 16 other zone, Bartonian (41.3 - 38.0 Ma)
• "In terms of Paleogene Mammalian Reference Levels (MP), Les Alleveys is slightly older than Robiac, the reference locality for MP16. In practice, all Bartonian (although not all Robiacian) European mammal localities are regularly referred to MP16"
Environment/lithology: fissure fill; limestone
Size classes: macrofossils, mesofossils
Collected by M. Weidmann in 1986
Collection methods: bulk, sieve,
• In 1852, S. Chavannes and A. Morlot discovered and collected from a horizontal karstic fissure in the quarry (...) It was from these coarse layers that almost all the fossils were collected (...) This fauna, referred to as “Les Alleveys 1852”, was revised by Hooker & Weidmann (2000).
•
•In 1986, in what we judge to be a continuation of the 1852 fissure, close to the original site, one of us (MW) extracted nearly 500 kg of sediment from the fissure (Fig. 1e), emptying it completely (...) It is this fauna, referred to here as “Les Alleveys 1986”, the study of whose rodents forms the subject matter of this paper.(From Hooker & Weidmann, 2007)
