AB In the Betic-Rif Cordilleras, recent works have evidenced the existence ofwell-developed Eocene (Ypresian-Bartonian) carbonate platforms rich in Larger BenthicForaminifera (LBF). Contrarily to other sectors of the western Tethys, like the Pyreneandomain in the North Iberian Margin, where these platforms started in the early Ypresian(Ilerdian), in the Betic-Rif chains, the recorded Eocene platforms started in the late Ypresian(Cuisian) after a widespread gap of sedimentation including the Ilerdian time span. Inthis work, the Aspe-Terreros Prebetic section (External Betic Zone) is studied. An Eocenesuccession with gravity flow deposits consisting of terrigenous and bioclastic turbidites, aswell as olistostromes with olistoliths, was detected. In one of these turbidites, we dated(with the inherent limitations when dating bioclasts contained by gravity flow deposits) themiddle Ilerdian, on the basis of LBF, representing a vestige of a missing Illerdian carbonateplatform. The microfacies of these turbidites and olistoliths rich in LBF have been describedand documented in detail. The gap in the sedimentary record and absence of Ilerdianplatforms in the Betic-Rif Cordillera have been related to the so-called Eo-Alpine tectonics(Cretaceous to Paleogene) and sea-level variations contemporarily with the establishmentof shallow marine realms in the margins of the western Tethys
