For this exercise the data comes from cores of marine sedimentary rocks from an Oligocene-Miocene sequence. A total of thirteen species of foraminifera were collected from the cores. Eight taxa were benthic foraminifera, and their preferred depth is shown below. Five taxa were planktonic foraminifera, with their age range shown below. 0-50m 50-150m 150-500m 500-1500m Globigerina ciperensis Lattorfian OLIGOCENE 23Ma Benthic Forams Nonion Globigering dissimilis Handawaia Uvigerina Bolivina grant Globigerinatella insueta Quinqueloculina Aquitanian Logena Planktonic Forams Valvulineria Bollvine marginata Gioborotalia fohl MIOCENE 20Ma Burdigalian Vindoronian Globorotlla menardi 16Ma 7Ma
