Ardara, facies C (Miocene of Italy)

Also known as Ardara-C

Where: Sardinia, Italy (40.6° N, 8.8° E: paleocoordinates 43.0° N, 3.7° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Calcari di Mores Formation, Early/Lower Miocene (23.0 - 16.0 Ma)

• "The Ardara Section (Fig. 3A) consists of 9 m of Miocene sediments within the Calcari di Mores Formation."

• formation-level stratigraphic resolution

Environment/lithology: shoreface; conglomerate

• "shallow-water, high-energy, shoreface environment"
• "Facies Ardara-C consists of a 30-cm-thick, oligomictic conglomerate (Fig. 4A), containing subrounded to rounded clasts with a maximum size of 5 cm. The clasts consist predominantly of granitic and quartz pebbles. These conglomerates are massive and predominantly clast supported. The fossil content consists of Amphiope and Clypeaster remains and reworked barnacles. When overlain by Facies Ardara-D, contact is sharp." "When underlain by Facies Ardara-B, contact is gradual."

Size classes: macrofossils, mesofossils

Collection methods: bulk,
