Bolbozoe bohemica Community, Ludlow, SW Sardinia (Silurian of Italy)

Where: Italy (39.4° N, 8.5° E: paleocoordinates 61.0° S, 53.3° E)

• coordinate based on political unit

• local area-level geographic resolution

When: M. fritschi linearis zone, Ludfordian (425.6 - 423.0 Ma)

Environment/lithology: marine; shale

• General for this succession of communities: "Unlike the Carnic Alps, the Silurian-Devonian of Sardinia displays a far less variegated facies picture, being almost exclusively developed in shallow to deeper pelagic environments, with the minor exception of the Emsian Mt. Padenteddu mud mound."

•For this community: "BA 4 to 5"

• No explicit lithologic data given here. Kriz (ref. 6282) says this community comes from calcareous shales. This would be consistent with general geologic setting stated by authors.

Size class: macrofossils
