资源简介:
Sediment depth is given in mbsf. Species abundance estimates (specimens > 63 µm): P = present but no abundance estimated, A = abundant (>10%), C = common (>1%-10%), F = few (0.5%-1%), VF = very few (0.1%-0.5%), MR = moderately rare (0.05%-0.1%), R = rare (0.01%-0.05%), VR = very rare (2 specimens), + = 1 specimen, - = looked for but not found. Symbols in parentheses = suspected reworking; cf = a similar but undescribed form. Ages are from Pälike et al. (2005, doi:10.2973/odp.proc.sr.199.213.2005).
