FIGURE 7. Family Textulariidae, Pseudogaudryinidae, and Valvulinidae. All scale bars = 0.1mm, unless otherwise indicated. 1, 2. Bigenerina nodosaria d'Orbigny, 1: MPC-26035 from sample 2 (Minebari Formation, PF5); 2: MPC- 26036 from sample 11 (Onogoshi F.,?PF1). Difference of coarseness and test size between specimens of figured 1 and 2 probably reflect eco-phenotypic variation and preservation. 3, 4. Textularia agglutinans d'Orbigny, 3: MPC- 26067, 4: MPC26068, both from sample 18 (Oura F.,?PF1). 5. Textularia cf. candeiana d'Orbigny, MPC-26069, broken specimen from sample 18 (Oura F.,?PF1). 6, 7.
