Concurrent range zone and partial range zone (ISG, Figure b and c): The interval between the documented lowest occurrence of one taxon and the documented highest occurrence of another taxon. Concurrent range zone is used when the fossil occurrence results in stratigraphic overlap of the taxa (Figure b).When such occurrences do not result in stratigraphic overlap, the interval zone may be called a partial range zone (Figure c).3.
