Preservation of Species Abundance in Marine Death Assemblages
Susan M. Kidwell

Supplementary Material

Part I: Live-dead datasets used in this analysis (arranged onshore to offshore). These marine molluscan datasets all consist of numerical abundance data for complete lists of live and dead species, including rare species; grain size data were available to determine how stations should be pooled into facies; both live and dead specimens were sieved from sediment using a single, known mesh size; each facies-level dataset is based on at least 2 samples. * = datasets included in analysis of Kidwell & Bosence 1991. # = datasets included in analysis of Kidwell in press. ^^ using authors' field samples only; live data gathered in the study area by earlier workers, which these authors pooled with their own, were collected using other (finer) sieve sizes.

Part II: Live-dead studies excluded from this analysis (arranged onshore to offshore). Reasons include one or more of the following: sieve size uncertain, live and dead taken from different sieve sizes, numerical abundance data not available, rare species omitted from species list, ambiguity whether live species are accompanied by dead shells, data not resolvable to facies-level, or other ambiguity in samples. Most of these can be incorporated in a larger and coarser analysis (in progress). * = dataset included in analysis of Kidwell & Bosence 1991. # = dataset included in analysis of Kidwell in press. + = dataset to be upgraded using unpublished data being made available by original authors.
