Cardiolinka sardiniana Comm., Lower Pridoli (Silurian of Italy)

Where: Sardinia, Italy (39.3° N, 8.7° E: paleocoordinates 59.0° S, 51.5° E)

• coordinate based on political unit

• local area-level geographic resolution

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

• In this study, isolated blocks were correlated on basis of contained conodonts. Fluminimaggiore Fm., Lower Pridoli, O. remscheidensis eosteinhornensis zone.

• member-level stratigraphic resolution

Environment/lithology: marine; shelly/skeletal, gray wackestone and calcareous shale

• "Relatively high diversity and low density correspond to favorable conditions for suspension beeders. Soft bottom conditions most sutable for infaunal and semi-infaunal forms...nektobenthic cephalopod shells provided substrate for epibyssate forms."

• 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 shells occur in the dark micritic to biomicritic lenticular limestone which originally formed horizons in the calcareous shales."

Size class: microfossils

Collection methods: Table 7 gives numerical abundances and inferred life habits of bivalves.
