Also known as Reef 1471
Where: Italy (39.1° N, 8.7° E: paleocoordinates 50.7° S, 44.4° E)
• coordinate based on political unit
• local area-level geographic resolution
When: Helderbergian to Helderbergian (419.2 - 402.5 Ma)
Environment/lithology: reef, buildup or bioherm; lithified lime mudstone
•For this community: "A depth of 70-80 m is inferred for the first growth stage of this 'mud-mound'; low energy conditinos are suggested by the presence of abundant llime mud and well-preserved pelmatozoan stems and calyces, while weak currents could have produced the telescoped fabrid, that is, the interpenetration of conical 'tentaculitids'. Very shallow conditions reuired for the final phase (not lower than 20 m), where currents and wave motion could affect the bottom. An inner shelf BA 3 position is suggested."
