Notes: The presence of turbidites and shallow-water (s.w.) debris, when recorded in DSDP/ODP publications, is noted in the Setting column. Absence is denoted by a shaded box. Presence in more than five samples is denoted by a tick. Sporadic or limited occurrences in less than five samples are shown with an X, followed by the number of samples in which the taxon was recorded.
