| We need to establish characteristic "paleontological signatures" or "fingerprints" for surfaces and components of a sequence. In order to do that we need to know how the fossils – as living organisms – respond to changes in sea level and, to an extent, sediment supply. | We need to establish characteristic "paleontological signatures" or "fingerprints" for surfaces and components of a sequence.

| Sequence //surfaces// provide the broad features that separate individual sequences and sequence components and also the mechanism by which sequences are biostratigraphically calibrated and therefore correlated on a well-to-well and eventually regional basis. | Sequence //surfaces// provide the broad horizons that separate individual sequences and //sequence components// ("systems tracts") and also the mechanism by which sequences are biostratigraphically calibrated and therefore correlated on a well-to-well and eventually regional basis. |

| | Readers should be familiar with the biostratigraphical principles and applications to (a) Biostratigraphy and Correlation and (b) Paleoenvironments (see [[start|Table of Contents]] on home page). Sequence biostratigraphy brings these two aspects together in a fully integrated way. |
