“…In Maud Rise sediments, we observed the first oc currence of H. edwardsii in CPla with H. teuriensis appearing shortly after that in CPlb. Overall, the genus Hornibrookina has been previously reported this low in the section only by Jiang and Gartner (1986), based on their light microscope study of the Brazos River section in Texas, but they identify the form as H. teuriensis.…”

Cores from Sites 689 and 690 of Ocean Drilling Program Leg 113 provide the most continuous Paleocene and Eo cene sequence yet recovered by deep sea drilling in the high latitudes of the Southern Ocean. The nannofossil-foramini fer oozes and chalks recovered from Maud Rise at 65 C S in the Weddell Sea provide a unique opportunity for biostrati graphic study of extremely high southern latitude carbonate sediments.The presence of warm water index fossils such as the discoasters and species of the Tribrachiatus plexus facilitate the application of commonly used low latitude calcareous nannofossil biostratigraphic zonation schemes for the upper Pa leocene and lower Eocene intervals. In the more complete section at Site 690, Okada and Bukry Zones CP1 through CP10 can be identified for the most part with the possible exception of Zone CP3. Several hiatuses are present in the sequence at Site 689 with the most notable being at the Cretaceous/Tertiary and Paleocene/Eocene boundaries.Though not extremely diverse, the assemblage of discoasters in the upper Paleocene and lower Eocene calcareous oozes is indicative of warm, relatively equable climates during that interval. A peak in discoaster diversity in uppermost Paleocene sediments (Zone CP8) corresponds to a negative shift in 518 0 values. Associated coccolith assemblages are quite characteristic of high latitudes with abundant Chiasmolithus, Prinsius, and Toweius. Climatic cooling is indicated for middle Eocene sediments by assemblages that contain very abundant Reticulofenestra, lack common discoasters and sphenoliths and are much less diverse overall.Two new taxa are described, Biscutum? neocoronum n. sp. and Amithalithina sigmundii n. gen., n. sp.

“…In recent years, semiquantitative studies documenting the changes that the calcareous nannoplankton underwent across the Cretaceous/Paleocene boundary have become available (Percival and Fischer, 1977;Romein, 1977;Monechi, 1979;PerchNielsen, 1979aPerchNielsen, , 1979bHerm et al, 1981;Romein and Smit, 1981;Thierstein, 1981;Jiang and Gartner, 1986;Pospichal and Wise, 1990).

“…This species is rare in early Paleocene assemblages from low-latitude regions (e.g., Biarritz: Perch-Nielsen, 1979c; Gubbio: Monechi, 1979;Zumaya: Percival and Fischer, 1977). Braarudosphaera bigelowii is absent at Hole 750A, although it is particularly abundant in the lower Paleocene of the Brazos River section (Texas: Jiang and Gartner, 1986), the Braggs section (Alabama: Thierstein, 1981), in the Rio Urola and Punta de San Telmo sections (Spain: Percival and Fischer, 1977), and at DSDP Sites 356 (South Atlantic; paleolatitude of 31° to 32°S at the end of the Cretaceous; Thierstein 1981) and 384 (North Atlantic; paleolatitude of about 33°N at the end of the Cretaceous; Thierstein, 1981).…”

“…7; Tables 8-10). Jiang and Gartner (1986) and Pospichal and Wise (1990) reported on the occurrence of H. teuriensis from the Brazos River section (Texas) and of//, edwardsii from Site 690 (Maud Rise, Weddell Sea), respectively, in the lowermost Paleocene. These reports and ours indicate that the frequency of H. teuriensis in earliest Paleocene assemblages varies with latitude, from scarce at low latitudes to abundant at high latitudes.…”

Calcareous Nannoplankton Changes across the Cretaceous/Paleocene Boundary in the Southern Indian Ocean (Site 750)

Changes in the composition of calcareous nannoplankton across the Cretaceous/Paleocene boundary at southern high-latitude Ocean Drilling Program Hole 750A are documented in this semiquantitative study. These changes are compared with changes described from other localities at high-and low-latitudes. This study provides additional data toward a detailed documentation of the paleontologic changes that occurred in the late Maestrichtian and the early Paleocene, despite limitations to the interpretation caused by coring gaps, drilling disturbance, and the presence of an unconformity at the boundary at this site.
