==High-resolution biostratigraphy==

High-resolution methods are quantitative approaches that, in addition to species ranges, use subtle paleontological changes (e.g., fossil abundance and diversity peaks). These data can be generated from actual counts of species abundance or from estimates of relative abundance. This detailed, time-consuming approach provides closely spaced correlations that are particularly effective for sequence stratigraphy studies<ref name=ch17r4>Armentrout, J., M., Echols, R., J., Lee, T., 1990, Patterns of foraminiferal abundance and diversity: implications for sequence stratigraphic analysis, in Armentrout, J., M., Perkins, B., F., eds., Sequence Stratigraphy as an Exploration Tool: Concepts and Practices in the Gulf Coast: Program and Extended and Illustrated Abstracts of the Eleventh Annual Research conference of the Gulf Coast Section of the Society of Economic Paleontologists and Mineralogists Foundation, p. 53–59.</ref> local or field correlation of reservoir units, or any problem where detailed resolution is vital. The use of multiple fossil groups in the same sections can greatly increase both the resolution and the level of confidence in the analysis.
