Kant, R.: Biometrische Untersuchungen an Ammonoideen-
Gehäusen [Biometric analysis of Ammonoid shells.]--

   A b s t r a c t : Constructional and morphological analysis of ammonoid shells provide new
and calculable features.  In addition, it leads to a better understanding of a given form and its
 origin.  With the aid of these features, different taxonomic problems can be solved which, so far,
 were completely ambiguous.  For a broader perspective, constructional morphology and "Bau-
 technik of other molluscs are briefly discussed.
