Notes: Abundance: A = abundant, C = common, F = few, R = rare. Preservation: G = good, M = moderate. Empty cell = the species was not observed in the sample. X = species exists on the slide but abundance was not noted. o = exactly one specimen found. sl = sensu latu, ss = sensu strictu, ? = uncertainty or difficulty in recognition of specimens (poor preservation, unusual morphology, or not clearly defined species).
