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.

The source code of the GONIAT online system will be made publicly available.
