Where: Italy (45.8° N, 9.5° E)
• Paleocoordinates: 31.4° N, 32.4° E (Wright 2013)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Sogno Formation, Tenuicostatum (184.2 - 182.9 Ma)
• The first bed lies in the lower part of the Sogno Formation, about 1.1 m above the base. Ammonites belonging to the Tenuicostatum Zone were collected below and above the first level, allowing a precise assignment to the lowermost Toarcian.
• bed-level stratigraphic resolution
Environment/lithology: marine; lithified, pyritic, carbonaceous claystone
Size class: macrofossils
Preservation: adpression
