Correlación de las escalas zonales de braquiópodos, foraminíferos y palinomorfos del tránsito jurásico inferior-jurásico medio en la Península Ibérica. Calibración con la zonación de ammonoideos

The zonal scales based on ammonoids defined in the Iberian Peninsula (Iberian and Betic Cordilleras, Lusitanian and Basque-Cantabrian Basins) are reviewed. These scales are compared with the Standard zonation established for the North Western European and the Mediterranean provinces, and calibrated with the regional scales based on brachiopods, foraminifers and palinomorphs. The useful elements to establish correlations between the Iberian area and with other basins of Western Tethys are signaled
