GONIAT is designed as a tool for investigations of the Paleozoic ammonoids, their paleogeographic distribution, and their biostratigraphic range. The underlying database provides not only determinations based on morphological characteristics, but also information on occurrence, duration, literature, and phylogenetic relationships of every taxon of family, genus, and species levels. GONIAT was originally available as a Windows application. The downloadable Windows version of GONIAT can be found here. The copyright of the data in GONIAT is held by the University of Tuebingen, GERMANY Please contact juergen . kullmann @ uni-tuebingen . de for information.
