Ittiri, facies C (Miocene of Italy)

Also known as Ittiri-C

Where: Sardinia, Italy (40.6° N, 8.5° E: paleocoordinates 42.5° N, 4.3° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Marne di Borutta Formation, Middle Miocene (16.0 - 11.6 Ma)

• "The Ittiri Section (Fig. 3B) consists of approximately 5 m of sandy sediments within the Marne di Borutta Formation."

• formation-level stratigraphic resolution

Environment/lithology: transition zone or lower shoreface; calcareous sandstone

• "moderate- to low-energy sublittoral environment"
• "Facies Ittiri-C consists of one meter of well-sorted, fine calcareous sandstone similar to Facies Ittiri-B, although the fossil content consists of irregular echinoids belonging to genus Schizaster and pectinid remains." When underlain by Facies Ittiri-B, contact is gradual.

Size classes: macrofossils, mesofossils

Collection methods: bulk,
