Plate 2. Scale bar for fig. 12 = 100 µm; scale bar for figs. 1-11, 13-17 = 100 µm. Codes after sample description are slide description and England Finder coordinates, respectively. 1. Fragments of siliceous microfossils, ash fragments, and opaque mineral grains outlining foraminifer skeletons. Sample 165-999B-15R-1, 24-26 cm, sl.4 F36/4. 2. Eusyringium fistuligerum. Relatively robust form. Sample 165-999B-36R-4, 7-9 cm, sl.1 Q26/4. 3. Eusyringium fistuligerum. Strongly corroded but identifiable from distinctive morphology. Sample 165-33R-1, 78-80 cm, cs.1 T30/0. 4-6. Carpocanistrum azyx. Progressive dissolution from a few pore bars (4) to a significant part of the test (6). Sample 165-999B-28R-1, 0-2 cm, sl.3 T2/3, Q7/0, T17/1. 7. Severely corroded radiolarian skeletons and ash fragments. Sample 165-999B-28R-1, 0-2 cm, sl.3 R5/3. 8. Phacodiscid sp. Cortical shell strongly fragmented because of in situ dissolution. Sample 165-999B-29R-5, 72-74 cm, cs.2 Q32/0. 9. Dictyoprora mongolfieri. Note good state of preservation. Sample 165-999B-28R-1, 0-2 cm, sl.3 Q1/3. 10. Lithochytris vespertilio. From one of the better preserved assemblages containing forms commonly unaffected by dissolution together with numerous forms in a stage of dissolution resembling the illustration. Sample 165-999B-35R-1, 73-75 cm, cs.1 C12/3. 11. Podocyrtis (Podocyrtis) papalis. Dissolution in collar region and distal part of thorax. Sample 165-999B-29R-1, 40-46 cm, ph.1 V42/2. 12. Calocyclas sp. Sample contains abundant ash and strongly dissolved radiolarian tests. Sample 165-999B-28R-1, 0-2 cm, sl.3 X17/4. 13. Podocyrtis (Lampterium) trachodes. Test showing strong signs of dissolution in the proximal part of the skeleton. Sample 165-999B-35R-1, 73-75 cm, cs.2 N22/2. 14-17. Lithocyclia ocellus. Progression of dissolution stages in the same sample from moderately well-preserved (14) to an almost unrecognizable form (17). Unless this progression can be recognized, it is impossible to identify forms such as that illustrated in (17). Sample 165-999B-35R-1, 73-75 cm, cs.2 D9/0; G10/3; K41/0; G11/0.
