The base of the zone, and of the Coniacian stage, is defined by the entry of the index species, which in the UK occurs at the Navigation Hardground in Kent (Gale & Woodroof, 1981; Bailey ''et al''., 1984; Gale, 1996). Thus, the base of the zone is in the topmost ''S. plana'' Zone of the standard macrofossil zonal scheme (Bailey ''et al''., 1984). There is no data regarding the upper limit of the ''F. petrocoriense'' Zone.
