| 0 | 27.5 | 14 | The sediments were intensely bioturbated with hollow and sediment-filled vertical, inclined and horizontal wotm tubes, bivalve traces with convex upwards layers from downward movement (bt, slice C) and concave upwards layers from slow upward motion (bt1, slice C). Trace bt2 was probably caused either by the rapid upward movements of a mollusc or a spoonworm. The spoonworm Echiurus echiurus probably caused the large lined structures (ee) observed in slice A. Some Scolicia isp. was also observed in the upper 15 cm of sediment. | ||
