Hodsoni Zone Franche-Comté (Jurassic of France)

Where: France (47.3° N, 6.0° E: paleocoordinates 37.4° N, 15.8° E)

• coordinate based on nearby landmark

• local area-level geographic resolution

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

• formation-level stratigraphic resolution

Environment/lithology: grainstone and limestone

• This flora inhabited lime muds in the intertidal zone, in a sheltered environment with a low tide amplitude. Low biodiversity, mangal area.
• 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.

Size class: macrofossils

Preservation: mold/impression, adpression, original carbon

Collection methods: bulk, mechanical,
