Also known as Bassin du Tage, Tagus basin, Tagus' basin, Tagus'
Where: Santarém, Portugal (39.3° N, 8.7° W: paleocoordinates 39.4° N, 9.8° W)
• coordinate based on nearby landmark
• small collection-level geographic resolution
When: MN 6 (13.7 - 12.8 Ma)
• The fossiliferous layer comes from approximately 10 meters below the surface. The presence of Anchitherium and absence of Hipparion excludes an Upper Miocene age. "..Megacricetodon crusafonti, Fahlbuschia darocensis, Cricetodon jotae are characteristic of mammalian MN6 unit, thus their ageis is nearly that of Sansan and Manchones (however the presence of Peridyromys hamadryas and Lagopsis verus do suggest, amidst this biozone, a somewhat later age than Sansan's).."
•Indirect correlation with marine formations, underlying oyster-bearing beds most probably in correspondance to the apogee of the same transgression that deposed near Lisbon "schlier" facies from VI-a division division (Serravalian, Blow's zones 10-13, Globorotalia meyeri zone).
• bed-level stratigraphic resolution
Environment/lithology: pond; lignite and mudstone
Size classes: macrofossils, mesofossils, microfossils
Collection methods: core, sieve,
• In the collections of the Centro de Estratigrafia e Paleobiologia das Universidades de Lisboa.

•The intial report on the lignitic clays is from a report on the geology, "Servico de Fomento Mineiro" M. Valdemiro B. Pereira, M. G. Zbyszewski the bone fragments. Antunes and Mein collected additional sediment, that was subsequently "washed" to recover the fossils.
