Ceratiocaris Community, Upper Ludlow to Lochkovian (Silurian to of Italy)

Where: Sardinia, Italy (39.4° N, 8.5° E: paleocoordinates 50.4° S, 44.8° E)

• coordinate based on political unit

• local area-level geographic resolution

When: Ludfordian to Ludfordian (425.6 - 393.3 Ma)

• Spans siluricas through woschmidti conodont zones. Individual arthropod species can be more finely designated stratigraphically (see Gnoli and Serpagli 1984, PBDB ref. 7253), but authors have lumped these with other faunal elements here.

Environment/lithology: marine; black lime mudstone

• 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: "This community interfingers with and alternates with the "Orthoceras" Limestone Community and the Scyphocrinites Community; it probably represents a BA 3-5 position (possibly BA 5 for the Mason Porcus occurrence)."
• "dark micritic limestone"

Size class: macrofossils
