[[:file:applied-paleontology_fig17-20.png|Figure 4]] shows an integrated paleoenvironmental interpretation of the E2.0 reservoir (Middle Miocene, [[Niger Delta]]). Lithofacies range from pebbly sandstones (S1) to mudstones (M2). The palynofacies are composed of the following substances:

The paleoenvironmental interpretation should be integrated with interpretations based on other data sources (e.g., sedimentology well log analysis, seismic) and plotted on wells or [[cross section]]s.

===Limitations===
Paleoenvironmental analysis can be limited by the ambiguity of the paleoecological significance of the fossils recorded. In general, reconstructions of paleoenvironment become less precise and less reliable with increasing geologic age as the affinities of ancient to modern forms become very distant.
