The Upper Cretaceous Terradets Limestone of the south Pyrenean Basin consists of two subunits, named the Lower Terradets and the Upper Terradets. In the Lower Terradets subunit, sedimentological features and fossil content permit distinguishing mid-ramp, bioclastic shoal and inner-ramp lagoonal facies associations, each characterized by a distinctive larger foraminiferal assemblage. Mid-ramp facies contain epibenthic, relatively small foraminifera like Cuneolina cylindrica, Dictyopsella cf. cuvillieri, Pseudocyclammina sphaeroidea, Nummofallotia cretacea, Fallotia? sp., Pararotalia cf. tuberculifera, Praestorrsella roestae and Praesiderolites praevidali. Bioclastic shoal facies are dominated by Orbitoides cf. tissoti, Praesiderolites douvillei, and Pseudosiderolites sp. The inner-ramp lagoonal facies contain a rich and diverse assemblage of epiphytes, like Ilerdorbis decussatus, Dicyclina schlumbergeri, and Cyclopsinella roselli n. sp., and epibenthic foraminifera, like Calveziconus lecalvezae and Orbitokathina campaniana. Strontium isotope stratigraphy indicates a middle Campanian age for the Lower Terradets limestone.

比利牛斯盆地（西班牙东北部）中坎帕阶浅水泻湖相的较大有孔虫和锶同位素地层学

南比利牛斯盆地的上白垩统梯田石灰岩由两个亚基组成，分别命名为下梯田和上梯田。在下 Terradets 亚单元中，沉积学特征和化石含量允许区分中斜坡、生物碎屑浅滩和内斜坡泻湖相组合，每一个都以独特的较大有孔虫组合为特征。中斜坡相包含底栖的、相对较小的有孔虫，如 Cuneolina cylindrica、Dictyopsella cf。cuvillieri、Pseudocyclammina sphaeroidea、Nummofallotia cretacea、Fallotia？sp., Pararotalia cf. 结核菌、Praestorrsella roestae 和 Praesiderolites praevidali。生物碎屑浅滩相以 Orbitoides 为主。tissoti、Praesiderolites douvillei 和 Pseudosiderolites sp。内斜坡泻湖相包含丰富多样的附生植物组合，如 Ilerdorbis decussatus、Dicyclina schlumbergeri 和 Cyclopsinella roselli n。sp. 和底栖有孔虫，如 Calveziconus lecalvezae 和 Orbitokathina campaniana。锶同位素地层学表明，Lower Terradets 石灰岩处于坎帕阶中期。
