Also known as Quercy Phosphorites
Where: Quercy, Midi-Pyrenees Region, France (44.2° N, 1.7° E: paleocoordinates 42.1° N, 2.0° W)
• coordinate based on nearby landmark
• local area-level geographic resolution
When: Robiac level zone, Bartonian (41.3 - 38.0 Ma)
• European Mammal Zone ('Niveau Repère') based on rodents
• member-level stratigraphic resolution
Environment/lithology: karst; phosphorite
Size classes: macrofossils, mesofossils
Collection methods: contains huge amounts of mammalian remains
•
•-Anchomomys aff. quercyi, Necrolemur cf. antiquus, and an additional maxilla and mandible of Pseudoloris parvulus (not included in the specimen count of 9) are all in the collections of l'Université de Montpellier (Godinot 1988).
•
•Insectivores and Chiropterans reported on by Sigé (1988) are in the collections of l'Université des Sciences et Techniques du Languedoc.
•Regarding the insectivores and chiropterans (Sigé 1988): Two localities "Locus 1 and 2" are indicated for all specimens, but because they are described as "two contiguous cavities of Bretou... [that] communicated in the same karstic unit, had the same filling and same fauna" they have been entered into the general Le Bretou locality.
