La Venta: middle ramp, Coral Faunas, Iberian Chain (Cretaceous of Spain)

Where: Spain (40.1° N, 0.2° E: paleocoordinates 28.6° N, 8.8° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Benassal Formation, Late/Upper Aptian (122.5 - 112.0 Ma)

• The succession studied belongs to the depositional sequence K.1.9 in which precise biozones were defined with orbitolines..., El Palasiet succession

• bed-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified packstone

• The corals are volumetrically important. They develop mainly tabular and massive morphologies (20-80 cm wide and few cm-80 cm high) although lamellar forms are abundant to the SW, towards the outer part of the ramp. The coral colonies are

•commonly encrusted by stromatolites (crusts up to 5 cm thick),coralline algae and some foraminifers (nubeculariids). Bioerosion of corals is also present. The coral association is not significantly different from that of unit 5...

• This level, with a thickness of up to 15 m, is represented by micritic bioclastic packstones made of various bioclasts (such as fragments of echinoids, corals, bivalves, red algae, calcispheres, orbitolines and other benthic foraminifers). Carbonate mud is conspicuous.

Size class: macrofossils
