Funtanazza A5 (Miocene to of Italy)

Where: Sardinia, Italy (39.6° N, 8.5° E: paleocoordinates 43.1° N, 2.2° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Aquitanian to Aquitanian (23.0 - 16.0 Ma)

• The marine sedimentary sequence at Funtanazza, containing the echinoid assemblages studied here, is a ca. 80 m-thick siliciclastic succession (Fig. 2)." "The studied section belongs to Unit E of" Units A to E of Assorgia et al. (1992) and "and approximately corresponds to the section D-D’ described by Assorgia et al. (1992)." "Radiometric dating using the 87Sr/86Sr ratio provided an age between 22.3 ± 0.3 Ma and 20.3 ± 0.2 Ma (Aquitanian to Early Burdigalian) for the succession (Barbieri et al., 1997)."

• group of beds-level stratigraphic resolution

Environment/lithology: shoreface; fine-grained sandstone

• Funtanazza Graben. "outer sublittoral environment, at moderate depth, with fine grained sand substrates and low to moderate water energy."
• "The echinoid assemblage occurs within an approximately 2 m-thick, well sorted, fine-grained sandstone deposit."

Size classes: macrofossils, mesofossils

Collection methods: Bulk collections
