Cuzal (Quercy Phosphorites) (Eocene to of France)

Where: Quercy, France (44.5° N, 1.5° E: paleocoordinates 41.3° N, 1.9° W)

• coordinate based on political unit

• outcrop-level geographic resolution

When: MP 13 to MP 13 (48.6 - 40.4 Ma)

• The fossiliferous fissure fill of Cuzal is found in a section of a

•shaft a few meters in diameter whose base connects with an

•larger empty cavity. The sediment in the upper

•part of the fissure fill within the shaft is composed of a yellow ochre clay

•rich in iron pisolites, fine quartzose elements, and phosphate nodules

•up to a decimeter size. The base of the fissure fill is composed of a

•redder clay, relatively homogenous and finely "litée".

• bed-level stratigraphic resolution

Environment/lithology: fissure fill; yellow mudstone and concretionary phosphorite

• Yellow ochre and red clay - see above.

Size class: mesofossils

Collection methods: bulk, sieve,

• The fossils etudies in this work were obtained by the washing-sifting of about 500 kg of sediment. Most of the mammal fossils are teeth.

•Laboratoire de Paléontologie de l'USTL à Montpellier.
