Funtanazza A1 (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. "The depositional environment of this assemblage is inferred as outer sublittoral with very fine sandy substrate and low to moderate water energy (Fig. 10, A1), sporadically affected by high energy events."
• "The echinoid assemblage occurs within an approximately 1.5 m thick, well sorted, fine-grained sandstone deposit."

Size classes: macrofossils, mesofossils

Collection methods: Bulk collections
