@article{Foraminifera:SourceID:182955, abstract = {Unilocular calcareous benthic foraminifers were studied in the size fraction greater than 73μm in 88 samples (upper Paleocene-Quaternary) from Deep Sea Drilling Project Site 525 (Walvis Ridge, bathyal zone, eastern South Atlantic). The total number of taxa (sp., subsp., formae) identified was 159; this number, however, is underestimating because many species were left unidentified due to their bad state of preservation and/or scarcity. Three species were described as new, one was renamed (nom. substit.) and 26 were identified only generically. The fauna recovered was quantitatively very poor: 38% of the taxa were represented by only one specimen. The most common foraminifers (in decreasing order of abundance) were: Pytine walvisi, n. sp., Fissurina fimbriata (Brady) 1884, Oolina cookei (Cushman) 1923, Fissurina auriculata auriculata (Brady) 1884, Lagenosolenia stelligera (Brady) 1884, Parafissurina uncifera (Buchner) 1940, P. lata (Wiesner) 1931, Pytine corn, n. sp., Oolina globosa (Montagu) 1803 and Lagena meridionalis Wiesner 1931. The following species were found in both the upper Paleocene and Quaternary sections: Fissurina fimbriata, Lagena acuticosta brevipostica Brady 1951, L. caudata (d'Orbigny) 1839, L. meridionalis, L. perexigua McCulloch 1977, Lagenosolenia axiformis (Matthes) 1939, Parafissurina fusuliformis Loeblich and Tappan 1953, Pytine corn and P. paradoxa (Sidebottom) 1912. The most numerous genera were Fissurina and Lagena, followed by Oolina, Parafissurina and Pytine. Comparison of the present data with our previous results for other DSDP Sites did not yield any interoceanic stratigraphic markers. The unilocular benthic calcareous foraminifers of the bathyal zone are of very limited value as guide fossils mainly due to their scarcity and broad vertical ranges. In addition, their use for stratigraphic purposes is seriously hindered by the state of disarray of their taxonomy. }, author = {Boltovskoy, E. and Watanabe, S.}, doi = {10.2307/1485971}, journal = {Micropaleontology}, pages = {1-27}, title = {Cenozoic monothalamous foraminifers from DSDP Site 525 (southern Atlantic). }, url = {https://marinespecies.org/foraminifera/aphia.php?p=sourcedetails&id=182955}, volume = {39}, year = {1993} }
