Abstract (in english)
   Habitats of hermatypic corals are shallow and turbulent marine environments that often lack biostratigraphic index fossils. For that reason many Cretaceous coral faunas are imprecisely dated or dated only on the basis of comparisons ith othar coral faunas. Using a large database on the taxonomy, stratigraphical and geographical distribution of corals in the Cretaceous, a method is proposed that will make it possible to specify the stratigraphical age of coral associations on the basis of their specific composition. In this process the stratigraphical range of the species (calculated before from well-dated faunas) is summarized and a probable age of the association proposed. The method does not only help to assess the biostratigraphical age of a fauna, but may also indicate whether a fauna represents an original composition or is a mixed association derived from reworked horizons or olistoliths.
   The methods can be applied to any other group of organisms, provided that the essential data for a comparison are available
