Many areas of paleontological enquiry, from questions of correlation to the characterization of macroevolutionary patterns, require estimates of taxonomic longevities. However, the fossil record is incomplete and biased and, as such, provides an incomplete sampling of true temporal ranges. “It is incomplete because many individuals, species, and higher taxa are not recorded as fossils. It is biased because the probability that a taxon is represented by a fossil is a function of the taxon's morphology, abundance, ecological habitat and spatial distribution, as well as the taxon's age.” (Pease, 1985, p. 272) To what extent do the inadequacies of the fossil record compromise our ability to estimate taxonomic longevities? What analytic methods exist for estimating true longevities from stratigraphic data, or for detecting situations where significant biases may be present? And perhaps most importantly, do analytic methods provide an effective way of dealing with the inadequacies of the fossil record?
