Abstract
The morass of divergent opinions that exist about the nature of the biostratigraphic zone are largely the result of semantic difficulties. The concept of time, with respect to biostratigraphic zones, has been used in at least three different ways: 1) as the linear passage of time on earth, 2) as the rocks deposited during a given interval of time, and-3) as the time represented by rocks bearing certain fossils. Claims that the third is the same as the second and that the second is the same as the first result from uncritical assessments of reality.
