Description
Uvigerina peregrina Cushman, 1923a Pl. 4, fig. 11
Uvigerina peregrina Cushman, 1923a, p. 166, pl. 42, figs. 7–10; Martin, 1981, p. 44, pl. 10, fig. 12–14; Milker & Schmiedl, 2012, p. 90, fig. 20.29.
Euuvigerina peregrina Barker, 1960, pl. 74, fig. 11–12.
Description: The test wall is calcareous and finely perforate. The test is broad, elongate, rounded in cross-section, triserial and covered in longitudinal costae. Later chambers become inflated with depressed sutures. The costae are separated by the sutures. The aperture is terminal, produced on a neck with a pronounced lip, bordering the edge of the aperture.
Remarks: The tests measure ~ 0.5 mm in cross section diameter and 0.8 mm in length. This species forms a major component (<50%) in all three cores.
Life strategy: Uvigerina peregrina is a shallow-infaunal species (Corliss and Chen, 1988), adapted to and most abundant under high organic carbon (Murray, 2006) and suboxic conditions (Kaiho, 1994).
Regional occurrence: This species is documented in middle Miocene sediments on the continental shelf of northern Namibia, south of the Kunene River mouth (this study). Schmiedl and Mackensen (1997) reported low to high abundances of U. peregrina in Pleistocene upper slope sediments of Namibia. This species is also abundant in Recent shelf to slope sediments along Namibia (Lowry, 1987; Schmiedl et al., 1997) and South Africa (Lowry, 1987).
