Scale bar = 31 nm. FIGURE 14. Peripheral area of a deep substrate pit showing transition from scallop shell surface (bottom right) to extensively etched pit base (top left) and a circular vertical boring (X). Scale bar = 18 Mm. FIGURE 15. Transition from normal scallop shell surface (left) to a deep pit (right) eroded by a large adult Cibicides refulgens. Removal of the foraminifer has torn away the uppermost calcite layer, exposing.
