Geography
Country: Italy
Coordinate: 45° 4' N, 7° 56' E
Coordinate basis: based on nearby landmark
Formation: Conglomerati di Cassano Spinola
Time interval: Late Miocene
Zone: MN13
Max Ma: 5.4
Min Ma: 5.33
Age basis: other
Geography comments: "in a gypsum quarry... on the southern slope of the Torino Hill" (coordinate based on Moncucco Torinese)
"Late Turolian (MN13)" and "Upper Messinian", within "the post-evaporitic phase of the Messinian Salinity Crisis"
the age estimate is based on cyclostratigraphy and on the occurrence of a 5.40 Ma ostracod fauna immediately below the vertebrates
"five fossiliferous levels were recognized in a three-meter thick succession (Fig. 2). The vertebrate fossil-bearing layers are named herein MCC3, MCC4, MCC5 and MCC7" but the specimens are not assigned individually to the layers, so they cannot be broken out

Environment
Lithology: claystone
Habitat comments: "The fossiliferous deposits mainly consist of silty and sandy clays including conglomeratic lenses" and the formation represents "fresh and brackish water" based on "moluscs and ostracods"
Methods
Life forms: rodents
Sampling methods: screenwash
Sample size: 1120 specimens
Sampling comments: "two tons of sediments were collected from each fossiliferous layer (MCC3, MCC4, MCC5, MCC7). The sediment was successively screenwashed and sieved"
