2 â Concept of zone Albert Oppel in France (1856) defined âzonesâ that are characterized by more than two taxa and having boundaries based on two or more documented first and/or last occurrences of the included characterizing taxa. This zone is now named âOppel zoneâ or â concurrent range zone â.It is a type of assemblage zone (see below). The concept of zone allowed subdivision of stages into two or more, smaller biostratigraphic units. âZonesâ constitute the basic unit of biostratigraphic classification. 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.
