Menat, west of Gannat (Eocene of France)

Also known as Sioule valley, Noir d'Auvergne

Where: Auvergne, France (46.1° N, 3.2° E: paleocoordinates 44.7° N, 0.6° W)

• coordinate based on nearby landmark

• basin-level geographic resolution

When: Late/Upper Eocene (37.2 - 33.9 Ma)

• A number of authors working on the fossil flora in the

•schists in this basin think that the age ranges from Eocene to Oligocene. Plants are in layers of silicious "sapropèle" produced by algae.

Environment/lithology: terrestrial; schist

• "Bituminous schist", large elongate pyrite nodules - specimens are preserved in the schists and the pyrite nodules.

Size class: macrofossils

Preservation: original carbon

Collection methods: Fossils are from the Collections of the Laboratoire de Géologie de la Faculté des Sciences de Clermont-Ferrand. The Trionyx specimen (very bad state of preservation) was found in a pyrite nodule.
