Pterinopecten (P.) cybele nesiotes Comm., Upper Pridoli, SW Sardinia (Silurian of Italy)

Where: Sardinia, Italy (39.4° N, 8.5° E: paleocoordinates 58.8° S, 51.5° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Fluminimaggiore Formation, Pridoli (423.0 - 419.2 Ma)

• In this study, isolated blocks were correlated on basis of contained conodonts. "Fluminimaggiore Fm., most probably the upper Pridoli."

• member-level stratigraphic resolution

Environment/lithology: marine; lime mudstone and calcareous shale

• "...left valves are more abundant (88%) than right valves..."
• General for this formation: "45-50 m thick alternation of black calcareous lenticular layers (peloid-cephalopod-ostracod wackestone-packstones grading to mudstones) with dark non calcareous pelites and shales. The upper part of the formation is characterized by more marly limestones and terminates with a crinoid bioclastic packstone horizon."

•For this community: "Disarticulated, commonly juvenile shells which occur in partly decalcified primarily dark micritic limestone nodules which were originally part of the calcareous shale sequence."
