Micropaleontological analysis of sixty (62) ditch cuttings rock samples collected from interval, 7800 feet to 12,002 well AD, located offshore western Niger Delta was carried out for the investigation their age and paleodepositional environment. Standard methods techniques foraminiferal sample processing were followed disaggregate microfauna matrix. The studied interval is predominantly made up...

Engelswies is an early Miocene vertebrate locality in southern Germany with a rich assemblage of terrestrial mammals, invertebrates and fossil plants. It is dated to 16.5-17.0 Ma based on magnetostratigraphy, biostratigraphy and lithostratigraphy, and includes among the faunal remains a hominoid upper molar fragment, the oldest hominoid so far identified from Europe. The evidence from Engelswie...

Whilst the "Cambrian Explosion" continues to attract much attention from a wide range of earth and life scientists, the detailed patterns exhibited by the terminal Proterozoic-Early Cambrian biotas remain unclear, for reasons of systematics, biostratigraphy and biogeography. In particular, recent changes in absolute dating of the Cambrian have refined the period of time that the fossil record m...

In the Hudson Bay/James Bay Lowlands, along the coasts of Banks Island, and along the eastern coast of Baffin Island are continuous and extensive sections in Quaternary sediments. These sections are rich in marine fossils, buried peats, and soils and contain a wide variety of glaciagenic sediments together with glacial marine units and littoral deposits. Lake muds are also fairly common. All th...

Since the early l990s the Chicxulub crater on Yucatan, Mexico, has been hailed as the smoking gun that proves the hypothesis that an asteroid killed the dinosaurs and caused the mass extinction of many other organisms at the Cretaceous-Tertiary (K-T) boundary 65 million years ago. Here, we report evidence from a previously uninvestigated core, Yaxcopoil-1, drilled within the Chicxulub crater, i...

Six Oligocene sequences and one earliest Miocene sequence were identified at Island Beach, Atlantic City, and Cape May, New Jersey, and correlated to the dO proxy of glacioeustasy and the eustatic record of Haq et al. by integrating lithostratigraphy, biostratigraphy, Sr isotopic stratigraphy, and magnetostratigraphy. Seven global dO increases are recognized by correlating dO records among deep...

Stratigraphy is the science that studies the strata, or beds, of (mainly) sedimentary rocks in order to extract from them the history of the earth’s surface. By grouping the bed successions in stratigraphic units and by studying their geometrical relationships with some simple rules, it creates the fundamental temporal relative framework necessary to understand the origin of the rock units them...

The appearance of detritus shed from mountain ranges along the northern margin of the Tibetan Plateau heralds the Cenozoic development of high topography. Current estimates of the age of the basal conglomerate in the Qaidam basin place this event in Paleocene-Eocene. Here we present new magnetostratigraphy and mammalian biostratigraphy that refine the onset of basin fill to ∼25.5 Myr and reveal...
