Where: Sardinia, Italy (39.4° N, 8.5° E: paleocoordinates 63.8° S, 56.3° E)
• coordinate based on political unit
• local area-level geographic resolution
When: M. colonus zone, Fluminimaggiore Formation, Homerian to Homerian (430.5 - 425.6 Ma)
• In this study, isolated blocks were correlated on basis of contained conodonts.Fluminimaggiore Fm., uppermost Wenlock to lowermost Ludlow (M. colonus Biozone).
• member-level stratigraphic resolution
Environment/lithology: marine; lime mudstone and calcareous shale
•For this community: "dark micritic lenticular limestone which originally formed a level in the calcareous shales"
Collection methods: Table 2 gives numerical abundances and inferred life habits of bivalves.
