Le Jadet Quarry (upper) (Cretaceous of France)

Also known as Saint-Martory

Where: Haute-Garonne, France (43.1° N, 0.9° E: paleocoordinates 35.1° N, 0.9° E)

• coordinate estimated from map

• small collection-level geographic resolution

When: Calcarenites du Jadet Formation (Ausseing Group), Late/Upper Maastrichtian (70.6 - 66.0 Ma)

• orig. assigned to Lestaillats Marls/Marnes de Lestaillats and Calcaire Nankin 2

• bed-level stratigraphic resolution

Environment/lithology: shallow subtidal; pebbly, yellow, argillaceous, sandy grainstone

• "The emergent terrains of this epoch extended markedly more to the west of this locality, while the Upper Cretaceous continental is present a dozen kilometers to the east of the quarry where the piece we described was found." "Shallow marine, possibly estuarine" (Buffetaut et al. 1991)

•(French translated by M. Carrano.)

• The "nankin limestone" which is exploited here constitutes a bed characteristic of the Upper Cretaceous of the Petits Pyrénées. It is a limestone of reddish tint, sometimes rose, slightly sandy." (French translated by M. Carrano).

•Bed is ochre-colored sandy calcarenites associated with soft clay pebbles"
