Taxonomic list

• List uses catagories, for example, R = rare...1 - 9 valves collected. C = common...10 - 99 valves collected. A = abundant...100+ valves collected.

•Categories are listed in the comments field, absolute abundances are given in the abundance field.

•Since taxa with greater than 99 specimens were not counted with absolute abundances, these were reported with category "A" for abundant.
