Spiroplectammina undetermined
Spiroplectammina sp. Pl. 1, figs. 1a–b Description: The chamber walls are agglutinated and well cemented. The test is flattened and broad, with the margins sub-rounded. In cross section, the test is trapezoid in shape. Chambers are initially planispiral, becoming biserial, with flush sutures. The ar...
