“…A warm climatic optimum is thought to have characterized the Mid-Miocene (Mid-Miocene Climatic Optimum -MMCO (~ 17.0-14.5 Ma)), and is also reflected by the "Monterey carbon isotope excursion" (Vincent and Berger, 1985;Woodruff and Savin, 1991;Holbourn et al, 2007). This period entailed a complex climatic optimum succeeded by a longterm climatic deterioration towards colder icehouse conditions (Flower and Kennett, 1994;Shevenell et al, 2004;Holbourn et al, 2007). The MMCO comprises a series of maxima and minima in δ 18 O records, suggesting a complex history of ice sheet fluctuation, but no near-field, high-resolution, Antarctic stratigraphic record of this time interval has yet been documented.…”

The pa per deals with sub-evaporite Badenian de pos its (Mid dle Mio cene, Paratethys) that dis play a sud den ap pear ance of globorotaliid taxa show ing pref er ences in the tax o nomic set and coil ing di rec tion. An in ter val of sinistrally coiled Jenkinsella mayeri with pro por tion ally coiled Globoconella bykovae is at the bot tom of the stud ied se quence. It is fol lowed by an in ter val of pro por tion ally coiled Jenkinsella transsylvanica. Pro por tion ally coiled Globoconella bykovae with a small num ber of propor tion ally coiled Jenkinsella transsylvanica are at the top of the Moravian (CPN 7) substage (Orbulina suturalis alias Lagenidae Zone). The sub-evaporite part of the Wielician (CPN 8) substage (Uvigerina costai alias Spiroplectammina Zone) be gan with a globorotaliid-bar ren in ter val (IIC biozone). It is fol lowed by biozone IID dis play ing three globorotallid peaks amongst globorotallid-bar ren de pos its. Only globoconellas are pres ent in all these three events. Pro por tion ally coiled Globoconella bykovae ap peared first. It is fol lowed by pro por tion ally coiled Globoconella minoritesta and sinistrally coiled Globoconella bykovae at the end of the biozone IID. Coil ing pref er ences of globorotaliids have been com pared to changes in the hy dro graphic re gime un fold ing dur ing the CPN 7 and CPN 8 in the stud ied area of the Paratethys. The study dis cov ers that the coil ing of globorotaliids re sponded se lec tively to the hy dro graphic changes. Globoconella bykovae is highly op por tunis tic and can tol er ate con sid er able tem per a ture changes. Spec i mens of this taxon per sist to coil pro por tion ally dur ing the sub-evaporite Badenian, ex cept for the shift to sinistral coil ing just prior to the Wielician evaporites. Sinistrally coiled Jenkinsella mayeri is the most sen si tive to hy dro graphic changes. This taxon re treated at the on set of the tem per a ture drop dur ing the mid-Moravian cryp tic cool ing. This cool ing is marked by the new jenkinsellid oc cur rence -pro por tion ally coiled Jenkinsella transsylvanica. Pro por tion ally coiled Globoconella minoritesta is pres ent in the mid dle of the IID globorotaliid peaks. The globorotaliid coil ing data, pre sented in this pa per, has been cal i brated to the global stra tig ra phy. The in te grated data (foraminifera, nannofossils, ox y gen and car bon sta ble iso topes, ra dio met ric mea sure ments) sup ports the view that the CPN 7/CPN 8 bound ary is co eval to the Langhian/Serravalian one.

“…It is commonly assumed that the high latitudes also played a decisive role during the Miocene period when Earth's climate was finally pushed into the bipolar glaciated mode of today (e.g. Flower and Kennett, 1994;Zachos et al, 2008). Despite their importance, detailed reconstructions of paleoenvironmental changes that occurred across this period are still seriously hampered by insufficient temporal control on marine sedimentary sequences, primarily due to the rare occurrence of traditionally used calcareous microfossils in these deposits (e.g.…”

Batiacasphaera bergenensis and Lavradosphaera elongata — New dinoflagellate cyst and acritarch species from the Miocene of the Iceland Sea (ODP Hole 907A)

A detailed palynological investigation of the almost continuous middle through upper Miocene sediment sequence of ODP Hole 907A in the Iceland Sea revealed the presence of a new species of the dinoflagellate cyst genus Batiacasphaera, and a new species of the acritarch genus Lavradosphaera. Batiacasphaera bergenensis sp. nov. and Lavradosphaera elongata sp. nov. are both morphologically distinctive and have well-defined stratigraphic range tops that are independently constrained by the pristine paleomagnetic record of Hole 907A. Both species disappeared within a narrow interval across the middle to late Miocene boundary, when smallscale glaciations on Greenland were large enough to reach sea level. The distinct morphology of the proposed species and their highest occurrence in this critical interval highlights their potential for future biostratigraphic application in the Miocene of the high northern latitudes, an area important for understanding the Late Cenozoic transition into a bipolar glaciated world.
