Time
| Period: | Paleogene | Epoch: | Eocene |
| Stage: | Priabonian | 10 m.y. bin: | Cenozoic 3 |

| Age range of interval: | 37.71000 - 33.90000 m.y. ago |
Stratigraphy
| Stratigraphy comments: 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. |
Lithology and environment
| Primary lithology: | schist |
| Lithology description: "Bituminous schist", large elongate pyrite nodules - specimens are preserved in the schists and the pyrite nodules. | |
| Environment: | terrestrial indet. |
Taphonomy
| Modes of preservation: | body,original carbon |
| Size of fossils: | macrofossils |
| Preservation of anatomical detail: | poor |
| Disassociated major elements: | some |
Collection methods and comments
| Collection excludes: | some genera,some macrofossils |
| Collection methods: | survey of museum collection |
| Reason for describing collection: | taxonomic analysis |
| Collection method comments: 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. | |
