Where: Italy (45.7° N, 9.3° E: paleocoordinates 31.0° N, 18.4° E)
• outcrop-level geographic resolution
When: Early/Lower Aptian (121.4 - 122.5 Ma)
• STRATIGRAPHIC RELATIONS: From unnamed lithostratigraphic unit, referred to as "transitional facies", that overlies the Maiolica Fm (Barremian), and is overlain by the "Livello Selli equivalenti and the Marne di Bruntino Fm (Late Aptian).
