I find myself in the position of discussing a rather unfortunate misnomer. In the first place, topics that traditionally have been called “quantitative biostratigraphy” seldom deal with quantities of anything. In the second place, much of “quantitative biostratigraphy” deals more with chronostratigraphy and geochronology than with biostratigraphy. The operational concept is time, not fossil content, although, of course, the fossil content is the starting point. Nonetheless, the phrase “quantitative biostratigraphy” is quite firmly entrenched in the working vocabulary and I will use it here. I will focus on three very different techniques that all involve stratigraphic correlation based on the ranges of fossils.
