Biochronology is now an advanced field with the recent development of computerized, quantitative methods yielding robust biochronological scheme

Ammonoids are, together with the conodonts, the most important stratigraphical tools for this interval. The present time resolution in terms of ammonoid biostratigraphy is highest in the Devonian (one zone has a mean

Furthermore, accomplishments and limits of ammonite biostratigraphy are presented, including aspects of evolution, preservational modes and
