Abstract
An Upper Cenomanian to Lower Turonian section has been sampled in the vicinity of Ganuza, northern Spain. Ammonoids, inoceramids and microfossils including foraminifera and calcareous nannofossils have been studied. We recognize three planktonic foraminiferal biozones: theRotalipora cushmani,Whiteinella archaeocretaceaandHelvetoglobotruncana helveticaZones. We also characterize theEiffellithus turriseiffeliiandQuadrum gartneriZones, based on...
