Where: Lombardy, Italy (45.9° N, 8.9° E: paleocoordinates 33.2° N, 15.4° E)
• coordinate based on nearby landmark
• outcrop-level geographic resolution
When: Arietites bucklandi ammonoid zone, Saltrio Formation (Calcari Selciferi Lombardi Group), Early/Lower Sinemurian (196.5 - 189.6 Ma)
• bed-level stratigraphic resolution
Environment/lithology: open shallow subtidal; massive, glauconitic, shelly/skeletal, white packstone
•
•"Thin sections of the layer embedding the bones (Fig. 1J) show bioclastic packstone and grainstone, with abundant and sometimes large fragments of crinoids, echinoids, ostracods, brachiopods, bivalves, gastropods, and benthic foraminifers (F. Berra, 2018, personal observation). The skeletal grains are often rounded and sometimes micritized, which indicates the presence of continuous reworking bottom currents."
Size classes: macrofossils, mesofossils
• feeding traces of marine invertebrates on bones (but not described)
Preservation: adpression
