Causses (Truc de Balduc section) TB 5 (Jurassic of France)

Where: France (44.5° N, 3.5° E)

• Paleocoordinates: 32.7° N, 26.1° E (Wright 2013)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Toarcian (184.2 - 174.7 Ma)

• formation-level stratigraphic resolution

Environment/lithology: open shallow subtidal; lithified marl

• Mid to lower shelf settings. Dark-gray fine-grained sediment point to high rates of sedimentation, high turbidity, intermittently lowered oygen values and soft to soupy substrate conditions.
• Argillaceous-marly sediments. Fossils were collected from marls.

Size class: macrofossils
