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 ...

The Diomedeoididae are an extinct group of the Procellariiformes (tubenoses), which appears to have been widespread in the epicontinental seas covering parts of Europe in the Oligocene. A fair number of skeletons and isolated bones of these birds are known from Oligocene and early Miocene sediments of Central Europe (Cheneval 1995; Mayr et al. 2002; Fischer 2003). A record from early Oligocene ...

During drilling of Leg 160 in the Eastern Mediterranean (April−May, 1995), Messinian (i.e., uppermost Miocene) facies were identified at a site at the base of the Cyprus slope (Site 968) and at two sites on the Eratosthenes Seamount (Sites 965 and 967). The new results can be compared with the recovery of Messinian evaporites from the Florence Rise west of Cyprus (Deep Sea Drilling Project Site...

The Oligocene–Miocene Maykop Group sediments, mainly composed of illite–smectite, store mercury in strongly variable concentrations from 10 to 920 μg/kg. Extremely high Hg levels (98–920 μg/kg) coupled with abnormal mercury-to-total organic carbon (TOC) ratios (Hg/TOC = 109 3000 μg/kg/wt%; TOC 0.2 wt% 1.2 wt%) were measured the Middle marine shales that deposited deepwater Indol–Kuban Basin und...

The geological history of the South Asian monsoon (SAM) before Pleistocene is not well-constrained, primarily due to a lack available continuous sediment archives. Previous studies have noted an intensification SAM precipitation and atmospheric circulation during middle Miocene (?14 Ma), but no records are test how changed prior this. In order improve our understanding monsoonal evolution, geoc...

Reaumuria is an arid adapted genus with a distribution center in Central Asia; its evolution and dispersal is investigated in this paper. Eighteen species of Reaumuria and nine species of two other genera in the Tamaricaceae, Tamarix and Myricaria, were sampled, and four markers ITS, rps16, psbB-psbH, and trnL-trnF were sequenced. The reconstructed phylogenetic tree is fundamentally consistent ...

Kangaroos and kin (Macropodiformes) are themost conspicuous elements of the Australasianmarsupial fauna. The approximately 70 living species can be divided into three families: (1) Hypsiprymnodontidae (themusky rat kangaroo); (2) Potoroidae (potoroos and bettongs); and (3) Macropodidae (larger kangaroos, wallabies, banded hare wallaby and pademelons). Here we examine macropodiform relationships...

[1] Paired benthic foraminiferal trace metal and stable isotope records have been constructed from equatorial Pacific Ocean Drilling Program Site 1218. The records include the two largest abrupt (<1 Myr) increases in the Cenozoic benthic oxygen isotope record: Oi-1 in the earliest Oligocene ( 34 Ma) and Mi-1 in the earliest Miocene ( 23 Ma). The paired Mg/Ca and oxygen isotope records are used ...

Abstract. Reconstructing Oligocene–Miocene paleoelevation contributes to our understanding of the evolutionary history European Alps and sheds light on geodynamic Earth surface processes involved in development Alpine topography. Despite being one most intensively explored mountain ranges worldwide, constraints elevation remain scarce. Here we present stable clumped isotope measurements provide...
