The genera Windsoporella mamet & rudloff emend. VaChard and Eovelebitella VaChard, are revised. Several species previously described in the literature are considered to be included in the genus Windsoporella emend.: W. radiata mamet & rudloff, Queenslandella jenkinsi mamet & roux, ‘Dasycladacée indéterminée’ mamet & roux, Diplopora tulayae Chanton-GüVenç, Velebitella pareyni mamet & roux, and Eovelebitella sp. sensu lyS, StamPli & Jenny. In addition, three other new species are described from carbonate rocks in Ireland, England, Morocco and Spain, W. clogrenensis n. sp., W. adamuzensis n. sp., and W.? but tevantensis n. sp. The last mentioned species might represent a transitional form between Windsoporella and Eovelebitella. The genus Eovelebitella seems to be limited to E. occitanica VaChard and similar species and subspecies, described here as E. occitanica marbellensis n. subsp. and E. betica n. sp. Other species previously considered by some authors as Eovelebitella, i. e., E. robertsii mamet & roux, Diplopora pusilla KoChanSKy & heraK, and D. constantini PonCet are no longer included in the genus. E. rob ertsii is designated as the type-species of the new genus Austreovelebitella n. gen. The genus Japhetella mamet & roux seems to be a nomen invalidum because its type-species is clearly an Eovelebitella, although the single existing illustration of this taxon is a Windsoporella.

Detailed palynological analysis of 230 core and sidewall core samples from the uppermost Plover, Elang, and lower Frigate formations, Bayu-Undan Field, Timor Sea, reveals the presence of diverse and moderately well preserved palynomorph assemblages (predominantly dinoflagellate cysts, together with acritarchs, spores, and pollen grains) that facilitate biostratigraphic, sequence stratigraphic, and palaeoenvironmental interpretations. The palynomorph assemblages, detailed systematically herein, comprise 96 spore and pollen species, 84 dinoflagellate species, and 15 acritarch species. Of these, the following 14 dinoflagellate cyst species are newly instituted: Ampulladinium aiax, Batiacasphaera macbethiae, Broomea fusticulum, Cauca bayuiana, Egmontodinium elongatum, Ellipsoidictyum fenestellum, Evansia? lacryma, Leberidocysta? strigosus, Leptodinium? ancoralium, Meiourogonyaulax baculata, Nannoceratopsis reticulata, Paragonyaulacysta? feneseptata, P. helbyi, and Yalkalpodinium playfordii. A further five species are not formally named due to a lack of adequately preserved specimens. One genus, Broomea COOKSONE viz., microphytoplankton diversity increases through transgressive systems tracts to a peak diversity at the maximum flooding surface; atypically brown wood frequencies may also peak at maximum flooding surfaces; and black debris frequencies increase higher in the highstand systems tracts. Palaeoenvironmental interpretations based primarily on palynological assemblages (especially microphytoplankton groupings and palynodebris distribution) provide a means to identify depositional settings in non-cored intervals. For instance, the occurrences of Ternia balmei, the Meiourogonyaulax group, the Ctenidodinium group, and the Rigaudella group represent an approximate gradient from very nearshore to offshore environments or possibly an increase in salinities from euryhaline to stenohaline conditions.
