Summary: A biostratigraphically complete Upper Maestrichtian-Danian sequence was recovered at ODP Leg 119 Site 738 on the southern Kerguelen Plateau. Planktonic foraminifers are abundant and well- to moderately preserved in all Upper Maestrichtian samples to within 6 cm of the Cretaceous/Tertiary boundary, where foraminifers are rare and poorly preserved due to increased sediment lithification. Lowermost Danian samples are also poorly preserved, but specimen abundance is sufficient for preliminary quantitative biostratigraphic analysis. Despite the poor foraminifer preservation, evidence is presented for paleoenvironmental change immediately below a thin, iridium-rich calcareous clay horizon that is recognized as the Cretaceous/Tertiary boundary. The recovered Maestrichtian planktonic foraminifers are identical to Austral Realm assemblages found in the southern South Atlantic region. All five species previously recognized as being endemic to this realm were recovered from Hole 738C. Lower Danian assemblages strongly resemble coeval low-latitude foraminifer faunas, whereas upper Danian assemblages differ only in the absence of indicator species, particularly the morozovellids.
