Champlitte Middle Bathonian dune microflora (Jurassic of France)

Where: France (47.6° N, 5.5° E: paleocoordinates 37.7° N, 15.3° E)

• coordinate based on nearby landmark

• small collection-level geographic resolution

When: Hodsoni Zone zone, Middle Bathonian (167.7 - 164.7 Ma)

• Bulk of fossil plants originate from a marine level at the transition from a group of bioclasic and oolithic calcarenites to a group of sublithographic limestones. Different locaties are slightly diachronous.

• bed-level stratigraphic resolution

Environment/lithology: dune

• shell sand dunes with some swamps

Size class: microfossils

Preservation: original sporopollenin

Collection methods: bulk, chemical, mechanical,

• This flora is an approximation for the missing palynological data from the Mamers region (see ref. 31318).
