“…The lowermost dated horizon within the marine sediments of the Berivotra Formation is within zone CF6, which spans from 69.1 to 69.6 Ma. Zone CF6 corresponds to the lower part of the Lithraphidites quadratus nannofossil zone at Berivotra, as also observed at El Kef, Tunisia (Pospichal, written commun., 1993;Li and Keller, 1998b) and Egypt (Tantawy et al, 2002). Though Manivit (1984) placed the FA of Lithraphidites quadratus near the base of planktic foraminiferal zone CF4 at DSDP Site 525A (stippled interval, Fig.…”

“…Recently, Li and Keller (1998a) subdivided this zonal scheme into nine Cretaceous Foraminiferal (CF) zones labeled CF1 to CF9 and cali-brated them to the paleomagnetic time scale of DSDP Site 525A. This new zonal scheme was subsequently applied successfully to sections in Tunisia (Li and Keller, 1998b;Li et al, , 2000Abramovich and Keller, 2002), Bulgaria , and Egypt (Tantawy et al, 2002;Keller, 2002). The new zonal scheme is particularly applicable to the Madagascar planktic foraminiferal assemblages because it was originally based on South Atlantic DSDP Site 525A, located at the same paleolatitude as Madagascar (Fig.…”

“…La presencia de caolinita (>10%) en posiciones cercanas al límite K/P también fue registrado en diversas localidades del globo al igual que en este estudio (Robert y Chamley, 1990;Ortega et al, 1998;Deconick et al, 2000;Tantawy et al, 2001). No obstante, su desaparición hacia el Daniano tardío no se condice con los registros de paleotemperaturas regionales del agua de mar que indican un aumento de la misma en el Cretácico Tardío (65,5 Ma), que se hace más evidente hacia el tope de la Formación Roca (Casadío et al, 2004), durante el Daniano tardío, situación que conduciría a un aumento de caolinita si existiera disponibilidad de agua en el ambiente.…”
