Geography
Country: France
Coordinate: 43.01° N, 2.73° E
Latlng basis: estimated from map
Time interval: Late Palaeocene
Ma: 56.0
Age basis: other
Geography comments: about 1 km NW of Albas (Fig. S1): coordinate estimated using Google Maps with difficulty but high accuracy
"Late-Latest Paleocene", correlated with the North American Clarkforkian 2 zone, and younger than the MP6b reference locality Claret but not clearly assigned to MP7
estimated to be "approximately 2.5 ky older" than the PETM onset based on carbon isotope data (Fig. 1), and therefore very close to 56 Ma

Environment
Lithology: claystone
Taphonomic context: fluvial deposit
Habitat comments: the section below the PETM consists of "sliciclastic-dominated alluvial deposits" and the exact fossiliferous level is a "dark gray clay" based on Fig. S3
Methods
Life forms: carnivores, primates, rodents, other small mammals
Sampling methods: screenwash
Sample size: 75 specimens
Net or trap nights: 0
kg screened: 500
Sampling comments: "collected via bulk-sampling (~500 kg), careful acid etching, and screenwashing techniques"
the specimen number prefixes are all UM, suggesting that the material is at the Université de Montpellier
