Schematic side-view representation of the vertical position (A–C) and top-view images of the sediment surface showing actual trajectories of foraminifera (D–F) related to the three vertical position categories, which can be taken by a foraminifera, i.e. surface (A,D) sediment–water interface, (B,E), and burrowed (C,F). Scale bars = 0.2 mm. From Deldicq et al.48.
