Continental sedimentation during early Cretaceous in the Central part of the Iberian basin took place in two sedimentary sub-basins, the Oliete and Aguilón sub-basins. The stratigraphic analysis carried out in these units allows us to define new lithostratigraphical units. The biostratigraphy analysis of these units was based on charophytes. The identification of regional unconformities allows to define three depositional sequences. These sequences span from the Valanginian or Hauterivian to the Early Barremian, and may be correlated to sequences K1.2 or K1.3, K1.4 and K1.5 or K1.6 D.S., previously defined by Salas et al. (1991) and Salas & Casas (1993) in the eastem Maestrazgo basin. These results indicate that the stratigraphic record of the central part of the Iberian basin is as completed as that of the margin of the neighbouring Maestrazgo, Aliaga-Peñagolosa and Cameros basins.
