This study was initiated in 1991, and originally was planned to be a summary of the sequence stratigraphy and naming of the new conodont species document that would be printed; the sometimes more detailed discourse about stratigraphic philosophy and observation to accompany the more detailed discussion and illustration of the conodont biostratigraphy was to be a digital supporting document. The research greatly evolved in scope in order to adequately deal with taxonomic, stratigraphic, and sequence stratigraphic issues.

Part A is largely a summary of the most essential elements of the conodont taxonomy, biostratigraphy, and sequence stratigraphy and is a printed document. Part B contains detailed conodont biostratigraphy, including an in-depth analysis of the problems of stratigraphic misplacement of species, clarifi cation of types, and more complete discussion of the sequence stratigraphic concepts and is included on a cd-rom in the back envelope of this volume. Some redundancy exists between Part A and Part B, but we felt the basic concepts are better served in this format.
