Basic information
Sample name: Albas

Reference: B. Marandat. 1991. Mammifères de l'Ilerdian moyen (Eocène inférieur) des Corbières et du Minervois (Bas-Languedoc, France). Systématique, Biostratigraphie, Corrélations. Palaeovertebrata 20(2-3):55-145 [ER 4434]
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
