Note: Shaded columns indicate samples with relatively poor preservation. X = presence, blank cell = not observed, - = absence specifically checked for, + = single specimen, ? = questionable identification. Abundance: VA = very abundant, A = abundant, C/A = common to abundant, C = common, F/C = few to common, F = few, R/F = rare to few, R = Rare, and VR = very rare. Data are semiquantitative; each half-rank step corresponds to approximately a factor of two difference in abundance. Very abundant means that the majority of all specimens were in this category; very rare refers to just two specimens.
