Notes: Based primarily on analysis of larger benthic foraminifers from core catcher samples. Foraminiferal assemblages: PF = planktonic foraminifers, ONBF = outer neritic/upper bathyal foraminifers, Sm Mil = smaller miliolids, LBF = rotalline larger benthic foraminifers, LBF = milioline larger benthic foraminifers, A = abundant; C = common; R = rare, lower case symbols indicate abundance of molds of larger foraminiferal shells. Paleowater depth: ? = uncertain.
