Comment:
Benthic foraminifers were counted according to the following scheme: 1 = present, 2 = 2 or more, 3 = 3-5, 4 = 5-10, 6 = 10-30, 7 = 30-50, 8 = 50-75, and 9 = 75-150. Because benthic foraminifers are not common in most samples, in many instances the numbers represent their true abundance in a sample. Only the bolivinids reached abundances of 6 or greater.
