Sediment depth is given in mbsf. Abundance estimates as follows: A = abundant, C = common, F = frequent, R = rare, B = barren, r = reworked, - = not found.
R = rare ( one specimen of a particular species encountered in 5-20 fields of view using a 40X objective and 10X ocular), F = frequent (one specimen in every 5 fields), C = common (one specimen in eve
