A hardiness zone (a subcategory of vertical zonation) is a geographically defined area in which a specific category of plant life is capable of growing, as defined by climatic conditions, including its ability to withstand the minimum temperatures of the zone (see the scale on the right or the table below).
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. The zone, or biozone, is the fundamental unit of biostratigraphic classification. A zone may be divided into subzones and/or grouped into superzones. Each biozone is given a unique name, which is compound and designates the kind of biozone.
