Morphometric and particle analysis (view source)

Data for the illustration were compiled from cores taken in the DeSoto Canyon area, eastern Gulf of Mexico. Significant shifts in shape (such as at {{Ma|7.5}}) can augment the resolution of existing biostratigraphic zonations. In addition to analysis from stratigraphic sections, refined paleoenvironmental interpretations can be obtained by comparing morphometric results from fossil populations (e.g., benthic foraminifera) with results obtained from analysis of existing species from known environments.
