(2003)Comparative characteristic of spore-pollen assemblages from the Son'e (late Eocene), Bui, Svetlovodnaya (late Eocene-early Oligocene), Amgu (late Oligocene-early Miocene), Dembi, Velikaya Kema (late early Miocene-earliest ...
-
(1997)Detailed Paleogene stratigraphy is based nowadays on the zonal schemes of different microfossil groups. The specific character of their development and the use of microphytofossil zonations in the regional stratigraphy of ...
-
(2003)The lower Paleogene sequence in the Middle Povolzhie (Ulyanovsk-Saratov syncline) of Russia is dominated by a terrigenous-rich siliceous facies with abundant and well-preserved siliceous plankton. Calcareous microfossils ...
-
(1993)Low paleolatitudes are very frequent in Eocene to Oligocene formations, particularly in the Tethyan mobile belt. These anomalies and their possible sources are discussed. They are neither due to unreliable results nor to ...

DISCOVERY OF A CHAMPSODONTID (PISCES, TELEOSTEI, PERCIFORMES) IN THE EOCENE OF THE NORTHERN CAUCASUS (2004)Eochampsodon elongatus gen. et sp. nov. is described from the Middle Eocene (Bartonian, Kuma Regional Stage) of the northern Caucasus (Gornyi Luch locality). This is the second genus of the previously monotypic family ...
-
(2003)Eocene diatoms and silicoflagellates from deposits of the Kronotskii Bay are the oldest known fossils of siliceous phytoplankton from the northwestern Pacific. More than 130 species of 59 diatom genera and 24 species of 5 ...
-
(2003)Dispersal of mammals into Europe at the beginning of the Eocene is conventionally interpreted as being solely from North America via the Greenland land bridge, as other routes were apparently unavailable because of the ...
-
(2001)The main evolutionary trends of the Tragulina are traced and the systematics and phylogeny of this taxon are revised based on the study of the comparative morphology of fossil and Recent species and on the estimation of ...
-
(2003)Fossil bivalves bearing oblique ribs first appeared in the Mid Ordovician but their diversity remained low during the Palaeozoic. The diversity soon increased after the Early Triassic, peaking in the Early Cretaceous. The ...
-
(1996)The Eocene evolution of the diatom flora of oceanic and epicontinental sea basins is discussed within the context of some abiotic factors. It was found that from the beginning of the Eocene to the end of the Lutetian, the ...
-
(2001)The shells of Modiolula parca sp. nov. are described from the Middle-Upper Eocene deposits of the Ukraine. Representatives of the genus are found in the Paleogene for the first time.
-
(2001)Huge amounts of arthropod cuticular fragments were found in the intestinal contents of 21 specimens of Thaumaturus intermedius, a teleostoid fish from the Messel oil shale. The cuticular fragments are identical to those ...
-
(1986)The Alpha Ridge is one of three subparallel trending ridges that cut the Arctic Ocean. It is roughly Late Cretaceous to Eocene in age, and seismic refraction records suggest it comprises a thick sequence of oceanic crust. ...
-
(2001)Flyschoid deposits of the Lesnaya Group that are exposed within northern Kamchatka are almost barren of identifiable fossils. The group is considered to be of the Late Cretaceous age on the basis of geological correlation. ...
-
(2002)The giant Mn ore deposits of the Paratethys are located on the slopes and/or margins of deep basins. The Eocene ocean and associated basins were strongly influenced by large-scale submarine hydrothermal activity which ...
-
(2001)The Antaramut–Kurtan–Dzoragukh (AKD) coal deposit is a previously unrecognized coal field in north-central Armenia. Coal has been known to exist in the general vicinity since the turn of the century, but coal was thought ...
-
(2002)We present paleomagnetic results of Paleocene welded tuffs of the 53–50 Ma Bogopol Group from the northern region (46°N, 137°E) of the Sikhote Alin volcanic belt. Characteristic paleomagnetic directions with high unblocking ...
-
(1988)The authors studied ten peridotite inclusions from basalts of the central Vitim Plateau namely eight granite-containing and one spinel-containing 1herzolite from recently discovered alkalic picrite tuff, thought to be of ...
-
(2001)This study is based on the isotope-geochemical characteristics of oils from 53 fields in the South Caspian Basin - from Upper Cretaceous, Eocene, Oligocene-Lower Miocene (Maykop), middle and the Upper Miocene (Diatom) and ...
