Kopaninoceras Community, Lochkovian (Devonian of Italy)

Where: Sardinia, Italy (39.4° N, 8.5° E: paleocoordinates 54.7° S, 47.8° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Lochkovian (419.2 - 410.8 Ma)

Environment/lithology: marine; limestone and siltstone

• 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: "A shallow water environment below wave base (outer BA 3-5 is suggested). The occurrences associated with Skenidioides indicate a BA 5 position."
• No lithologic data given for this community. Entire sequence is limestone-shale succession. Gnoli (1982, PBDB ref. 7254) descirbes this material as coming from "Lower Devonian beds, consisting mainly of nodular limestones and siltstones."

Size class: macrofossils
