Figure 2. Depth ranges of key Pliocene-Quaternary planktonic foraminiferal zonal species and other stratigraphically useful taxa in Hole 1011B, California margin. California margin (CM) planktonic foraminiferal zones shown at left. Question mark and dashed lines represent range extensions that are questionable or based on rare specimens.
