Distinctive carbonate facies can be used to recognize a spectrum of environments that include peritidal areas, lagoons, shoals, reefs, ramps, slopes, and deep marine settings.

This is insufficient to describe the full natural variability of the climate system, which makes attribution of observed changes difficult. We want to know if the changes observed in the recent past are unusual compared to pre-industrial climate variability. If they are it is more likely that they are anthropogenic, if not they could well be natural.

This chapter provides a starting point for identifying fossils by providing several summary diagrams and numerous photographs.

Common microfossils not covered elsewhere in this chapter include radiolarians, diatoms, foraminifera, ostracods, and conodonts.

There are two primary classification schemes: the Dunham scheme is more useful for outcrop and hand sample and the Folk scheme is more useful for thin sections.
