| The Working Group proposes only one modification to its current zonation of the Mediterranean Region, the addition of a cristatum Subzone in the lower part of the inflatum Zone (upper Albian). But in the light of newly published research it highlights levels/areas where further work is required, especially to resolve conflicting zonal schemes. It also proposes a 'Tethyan Province' zonation for the middle Albian. Alternative correlations for the Boreal/Tethyan Valanginian to Barremian stages are tabulated, one based on ammonite evidence alone, the other with additional biostratigraphical data coupled with sequence stratigraphy and magnetostratigraphy. |

| Although the so-called 'standard' ammonite zonation of the Albian contains index species which occur in the Tethyan province, the scheme largely reflects the faunal succession in the European faunal province with its endemic sonneratiinid and hoplitinid faunal elements. Workers in the Tethyan province, stretching from South America in the west to Australia in the east, including southern Africa, Madagascar and India, face problems in the correlation of their successions with this so-called 'standard' scheme. There are other problems in that the succession of hoplitinid ammonites used in the biostratigraphy of European Albian sediments allows a far more detailed zonation to be made than in the case of some of the longer time-ranging Tethyan forms.
