The Urbanizacion Montsec site (Cretaceous to of Spain)

Where: Cataluña, Spain (42.1° N, 0.9° E: paleocoordinates 32.5° N, 2.3° E)

• coordinate estimated from map

• outcrop-level geographic resolution

When: Arén Formation, Late/Upper Campanian to Late/Upper Campanian (83.5 - 66.0 Ma)

• formation-level stratigraphic resolution

Environment/lithology: lagoonal; sandstone and limestone

• The northward-dipping grey sandstones of the Aren Forma- tion are capped with thick white lagoonal limestone of the Tremp Formation, overlain by a rudist-bearing marly layer, the Hippuritella castroi horizon (Fig. 2). The white lagoonal limestone is sharply divided by the intercalation of a fine-grained sandstone wedge, about 10 m thick, of the Aren Formation, which thickens westwards and rap- idly diminishes eastwards (Fig. 2). The lower part of the white lagoonal limestone pinches out westwards and dis- appears within the Aren Formation, while the upper part continues westwards capping the Aren Sandstone. A rich monospecific assemblage of eggshell fragments from the new ootaxon is concentrated on the reddish upper surface of the Aren sandstone wedge. The outcrop is affected by NNE–SSW directional faults.

Size classes: macrofossils, mesofossils

Preservation: original calcite
