Abstract

Fossil deep-sea corals have been collected from dredges and sediment cores from the outer shelf and middle slope at the northern Argentine Continental Margin (37°–38°S). They have been identified as Flabellum (F.) thouarsii and Bathelia candida. Both species inhabit nowadays the outer shelf and the upper and middle slope of eastern South American coasts, but they had never been described as fossils. The integration of planktonic foraminiferal assemblages and one accelerator mass spectrometry ¹⁴C dating of a fragment of a coral branch belonging to B. candida allowed a precise biostratigraphic and geochronological control, indicating a Late Pleistocene age for the first fossil representatives of this species.
