Nowakia-Styliolina Community, Lower Devonian, Sardinia (Devonian to of Italy)

Where: Italy (39.5° N, 9.0° E: paleocoordinates 50.7° S, 45.2° E)

• coordinate estimated from map

• local area-level geographic resolution

When: Helderbergian to Helderbergian (419.2 - 402.5 Ma)

• Community spans Late Pragian to Early Emsian.

Environment/lithology: marine; limestone and 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: "Although found also at the boundary with the Coral-Stromatactis Community [PBDB coll. 26128], this is typical of limestones intercalated with shales or with massive limestones, where this community is dominant; BA 5-6."

Size class: macrofossils
