Australian Eocene-Oligocene Ostracoda have been little reported hitherto, this paper representing the first substantial taxonomic study. The 80 species which we identified came from Late Eocene Gull Rock Member of Blanche Point Formation in Willunga Embayment, South Australia (16 species) and lower fossiliferous bed Oligocene Angahook at Bells Headland, Victoria (70 species); only 6 are common ...

[1] Tectonic changes that produced a deep Tasmanian Gateway between Australia and Antarctica are widely invoked as the major mechanism for Antarctic cryosphere growth and Antarctic Circumpolar Current (ACC) development during the Eocene/Oligocene (E/O) transition ($34–33 Ma). Ocean Drilling Program (ODP) Leg 189 recovered near-continuous marine sedimentary records across the E/O transition inte...

We describe a new species of Rodentia (Mammalia), Argyromys cicigei sp. nov. from Toglorhoi (fossil bed TGW-A/2a) in Mongolia and Ulantatal (fossil beds UTL 1 and UTL 7) in China. Its tooth morphology differs from the type species Argyromys aralensis from Akespe in Kazakhstan by smaller size and simpler structures. Argyromys has been assigned in different families of Muroidea, such as Tachyoryc...

The evolution of the western Mediterranean of an 'interna1 zone plate' by the mechanism basin is considered. The Provence basin invoked by Karig. Lower or middle Miocene results from the Oligocene migration of Conica squeezing of the interna1 zones against the and Sardinia southeastwards. The North North Afncan platform caused ejection of the African basin was created by the dislocation flysch ...

Drilling offshore from Cape Roberts, Antarctica, has enabled recovery of a 1472-m cumulative record of late Eocene–early Miocene history of sedimentary basin development and climate change in the Western Ross Sea. In this paper, we synthesize the results of palaeomagnetic analyses carried out on the CRP-1, CRP-2 and CRP-3 sediment cores, and present a chronology for the recovered Eocene–Miocene...

At Ocean Drilling Program (ODP) Site 1090 (lat 42 54.8 S, long 8 54.0 E) located in a water depth of 3702 m on the Agulhas Ridge in the sub-Antarctic South Atlantic, 300 m of middle Eocene to middle Miocene sediments were recovered with the advanced piston corer (APC) and the extended core barrel (XCB). U-channel samples from the 70–230 meters composite depth (mcd) interval provide a magnetic p...

BACKGROUND The family Phyllanthaceae has a predominantly pantropical distribution. Of its several genera, Bridelia Willd. is of a special interest because it has disjunct equally distributed species in Africa and tropical Asia i.e. 18-20 species in Africa-Madagascar (all endemic) and 18 species in tropical Asia (some shared with Australia). On the basis of molecular phylogenetic study on Bridel...

A new species of Apatemyidae, Sinclairella simplicidens, is based on four isolated teeth that were screenwashed from fissure fillings at the late Oligocene Buda locality, Alachua County, Florida. Compared to its only congener Sinclairella dakotensis, the new species is characterized by upper molars with more simplified crowns, with the near absence of labial shelves and stylar cusps except for ...

Rodents of the extant family Gliridae, commonly called dormice, are common in European faunas since early Eocene. Here we study for first time specimens from St-Martin-de-Castillon C (France, Oligocene) previously reported as Gliravus aff. majori and Pseudodryomys fugax. We now refer them to Butseloglis tenuis Microdyromys misonnei. Besides French material, new Montalbán 1D (Spain, studied. The...
