Taxonomic list

• Data is presented in two ways in the paper: as presence/absence data for all 34 sampled horizons, and standardized abundances for 23 of those horizons. Where available, abundance data is entered. Counts from bulk sampling "were adjusted uniformly for fragmented and single valve occurences by multiplying through a ratio--4 fragments or 2 valve equal to one occurence." Standardization means "bulk sampling counts were standardized by sample weight".
