Plate 3. Evidence of nannofossil incorporation in foraminifera test from sample 1215A_8H-03_130-132. A, C &E are broken pieces of foraminifera test resulting from extreme dissolution. Note in the arrows showing nannofossil incorporation in foraminifera test. B) is the enlarged part of T. selmensis showing a combination of secreted hyaline test and embedded coccolith plates. This test composition suggests that foraminifera could calcify in dual processes (agglutinating and secreted hyaline). D) shows advanced stages dissolution and thinning of O. umbonatus? test wall with fragmentation setting in. G & F are further evidence of incorporation of nannofossil in foraminifera
