Truc de Balduc - sections PI1, Pl 2, Pl 6, Pl7, Pl 8, Pl 9, Pl 10, RsT-Pl4 (Jurassic of France)
Where: France (44.5° N, 3.5° E: paleocoordinates 32.8° N, 13.3° E)
• coordinate estimated from map
• outcrop-level geographic resolution
When: Late/Upper Pliensbachian (189.6 - 183.0 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
