Patterns of biofacies distribution reinforce other lines of evidence for variations in relative sea level, such as those illustrated by the distribution of clinoforms (Figure 4-27). When overlain on maps of lithofacies and seismic facies, biofacies patterns that complement other environmental interpretations increase confidence in reconstructions of the geologic history of the study area, including depositional cycle definition and subdivision and facies distribution of potential reservoir and seal rocks (see Armentrout et al<ref name=ch04r12>Armentrout, J.
