| 0 | 27 | 14.8 | Radiographs of sediment slices D and E with hollow and filled worm tubes, bivalve and echinoids. Legend: hb:hollow tube, Ilt:large lined trace made by Echiurus echiurus. The straight (mm-size) linings in the radiograph are over 2 cm apart and are composed of compressed sediment (lined walls). | ||
| 0 | 27 | 14.8 | Radiographs of slices ABC with numerous hollow and filled worm tubes and traces left by upward (without concentric traces) and downward (concentric traces) movements of Molluscs. Legend: hb:hollow tube, fb:sediment-filled tube, bto:traces left by bivalves, almost without layering, btu:traces left by bivalves, sediment layers are convex upwards. | ||
| Bemerkungen zu den Radiographien: Radiographies 0-27.3 cm. Schicht A, B und C sind parallel hintereinander mit ca. 8 cm Abstand, D und E sind senkrecht am Rand entnommen worden. | |||||
