Praeorbulina glomerosa curva Bolli et al., 1985, p. 199, figs. 23.5, 24.6; Kennett & Srinivasan, 1985, p. 82, pl. 18, figs. 3-4. Description : The test surface is cancellate-spinose. The test is trochospiral, globular and semi-circular or subspheroidal in cross section. The final chamber envelops earlier chambers. The proportion of the enveloping chamber is variable, with 40 to 70% of the test that can be covered. Apertures form slits along the margins of the ultimate, penultimate and earlier chambers. Numerous narrow slit-like apertures can cover the test along the sutures. The sutures become more incised in the later chambers. Remarks: This species occurs in minor abundances in the cores. The tests are moderate in size, measuring up to 0.4 mm in diameter. Environmental preferences: Praeorbulina curva is considered to be a temperate to warm water tropical species (Kennett & Srinivasan, 1983). Global stratigraphic range : This species has been recorded to occur from the early (Burdigalian) to middle Miocene – Langhian (Kennett & Srinivasan, 1983; Wade et al., 2011). Regional occurrence: Praeorbulina curva is documented to occur in middle Miocene-aged sediments of the northern Namibian continental shelf, south of the Kunene River mouth (this study). : Published as part of Bergh, Eugene W. & Compton, John S., 2022, Taxonomy of Middle Miocene foraminifera from the northern Namibian continental shelf, pp. 1-55 in Zootaxa 5091 (1) on page 36, DOI: 10.11646/zootaxa.5091.1.1, http://zenodo.org/record/5840434 : {"references": ["Blow, W.
