FIGURE 21. Family Globigerinidae, All scale bars = 0.1mm. 1. Globigerinoidesella fistulosa (Schubert), MPC-25967 from sample 8-2 (Yonahama Formation, PL4). Poor preservation is due to serious recrystallization. 2, 3. Globoturborotalita decoraperta (Takayanagi and Saito), 2: MPC-25990 from sample 6 (Yonahama F., PL2); 3: MPC-25991 from sample MK01 (Yonahama F., PL2). 4, 5.
