The sequence of biostratigraphic events (i.e., highest and lowest occurrences) is frequently different, to a greater or lesser degree, between even nearby wells or outcrop sections. ''Probabilistic biostratigraphy'' is a statistical technique that determines the probability a sequence of biostratigraphic events will occur in a specific order. Probabilistic correlations, accordingly, are based on the sequence of events and not on the stratigraphic intervals or distances between them.

Probabilistic techniques can help us recognize objectively the most probable sequence of events and therefore can be used in (1) constructing interval zones and zonations and (2) evaluating the reliability of particular biostratigraphic events in local or regional settings.
