Loulle tracksite (Jurassic of France)

Where: Franche-Comte, France (46.7° N, 5.9° E: paleocoordinates 37.7° N, 15.0° E)

• coordinate stated in text

• outcrop-level geographic resolution

When: Taramelliceras hauffianum ammonoid zone, Morillon Formation, Early/Lower Kimmeridgian (155.7 - 150.8 Ma)

• upper part of formation. Hauffianum Subzone (Bimammatum Zone); Orig. Upper Oxfordian

•Also assigned to Pierre bleue de Loulle (late Oxfordian)

• bed-level stratigraphic resolution

Environment/lithology: estuary or bay; bioturbated dolomite

• "a tidal-flat environment from intertidal to supratidal zones, punctuated by frequent flooding and emersion phases leading to desiccation, microbial mat development, and new sediment inputs"
• "Lithological and sedimentary structures are characterized by laminated dolomite in centimetric beds with internal millimetric lamination. Nine successive surfaces (S1 to S9 in Cariou et al., 2014) can be observed, eight of them revealing dinoturbation (true tracks, undertracks, or overtracks"

Size class: macrofossils

Preservation: mold/impression, trace
