The zone, base of biostratigraphy

The zone, base of biostratigraphy
Bulletin of the American Association of Petroleum Geologists (December 1951) 35 (12): 2582-2596


A short review of the historical development of the term "zone" is given. Faunas can not be used for chronological paralleling, excepting within small areas. Some rules of phylogenetic evolution are given, offering the basis for the geological measuring of time. Zone is the duration of life-time of a species which is determined phylogenetically, and whose ancestor and descendant are known. Zone, therefore, is a chronological term. The terms partial zone, subzone, horizon, and combined-continued zone sequence are explained. Discrepancies of zone sequences can be caused by wrong determination of zone fossils, careless collecting, overlooked resedimentation of fossils, different interpretation of species, migrations, and confusion of the terms zone, partial zone, and horizon.
