Extract

The utilization of taphonomic information to formulate biostratinomic models for modern and ancient assemblages has become a potentially powerful tool in paleoecologic analysis. The division of fossil assemblages into discrete suites of taphonomically-similar material adds an extra dimension to the interpretation of depositional setting and paleoecologic structure (Brett and Baird, 1986; Speyer and Brett, 1986, 1988; Speyer, 1987). This approach uses the hypothesis that taphonomic alteration varies in a predictable way with depositional setting. In other words, each specific environment (e.g., low-salinity muddy bay, storm-dominated clastic shelf) is characterized by a unique suite of physical, chemical and biological processes: these processes imprint a unique and predictable “taphonomic signature” on the death assemblage.
