• Resumen

  • During late Bajocian times, wide areas of the eastern Basc-Cantabrian Range were covered by sponge facies. Small-size sponge buildups and poorly sorted sponge and ammonite wackestone facies were developed in open platform areas, whereas grain-supported, bioclastic and tuberolitic packstone facies, accumulated in the shallower and waved areas of the platform. The basin was mainly open to the East as shown by both the submesogean affinity of the recorded ammonite associations and the facies distribution of the platform.
