UVIGERINELLOIDES: A NEW ROTALIID BENTHIC FORAMINIFERAL GENUS [PDF]
Science Heritage JournalThis study describes a new Paleogene Rotaliid genus Uvigerinelloides from the middle Oligocene, Septarienthon of Hermsdorf, near Berlin, Germany. It is characterized by fusiform triserial perforate calcareous test, chambers regularly triserial throughout,

Connecting the distribution and diversification of marine plants
Oikos, EarlyView.Integration of the evolutionary history with distribution of extant species is necessary to explain present‐day diversity, particularly for ‘foundation' species, such as seagrasses, which create habitats of socioecological relevance. Here, we resolved if varying evolutionary history of seagrass families has imprinted the distribution ranges of extant ...

Petrographic and geochemical evidence for determining the provenance of the Nari Formation, Pakistan
Geofísica InternacionalThe geochemical and petrographic characteristics of the Nari Formation (NF) have been thoroughly examined at the Haji Haroon section in the Lower Indus Basin (LIB), located in the Northern Laki Range, approximately 20 kilometres south of Therhi village ...

A finding of Oligocene primates on the European continent [PDF]
Proceedings of the National Academy of Sciences, 1999 In this paper, we provide evidence that contrary to the current view, primates on the European continent did survive the dramatic extinction/origination event across the Eocene/Oligocene boundary 34 million years ago that severely affected the Eurasian mammal communities (the European “Grande Coupure” and the Asian “Mongolian Remodeling”). The survival

PLANTS, PEOPLE, PLANET, EarlyView.Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Cementation scenarios for New Zealand Cenozoic nontropical limestones
, 1996 Cenozoic limestones are widely distributed in New Zealand, especially in the Oligocene-earliest Miocene in both islands, and the Pliocene-Pleistocene in North Island.

River Research and Applications, EarlyView.ABSTRACT As ecosystem engineers, beavers (Castor canadensis) modify river corridor form through dam building. When beavers are removed from a river corridor, their unmaintained dams wash out, altering the stream's hydrologic regime. The assumption that beaver dams increase floodplain connectivity is frequently presumed but has not been directly ...

Antarctic topography at the Eocene–Oligocene boundary [PDF]
Palaeogeography, Palaeoclimatology, Palaeoecology, 2012 We present a reconstruction of the Antarctic topography at the Eocene–Oligocene (ca. 34 Ma) climate transition. This provides a realistic key boundary condition for modeling the first big Antarctic ice sheets at this time instead of using the present day bedrock topography, which has changed significantly from millions of years of tectonism and erosion.

, 1989 Geochemical analyses of the middle Eocene through lower Oligocene lithologic Unit IIIC (260-518 meters below sea floor [mbsf]) indicate a relatively constant geochemical composition of the detrital fraction throughout this depositional interval at Ocean ...
