Paleocene stratigraphy in Egypt

Journal of African Earth Sciences, 2016
Abstract The Egyptian Paleocene is widely distributed with vertical and lateral facies changes geographically separated and subject to different tectonic and sedimentary regimes. Five coeval facies associations of the Paleocene outcrops are identified and named from south to north: Garra El-Arbain, Nile Valley, Farafra, Sinai, and Southern Galala ...

Nitrification in Paleocene Shale

Science, 1974
Exchangeable ammonium nitrogen is present in Paleocene (Fort Union) shale below a depth of 10 meters in North Dakota and eastern Montana. Above 10 meters, exchangeable ammonium nitrogen is nitrified in situ. The lack of viable nitrifying organisms and the probable lack of oxygen prevent in situ nitrification below 10 meters.

Mechanisms of Climate Warming at the End of the Paleocene

Science, 1999
An abrupt episode of global warming marked the end of the Paleocene epoch. Oxygen and carbon isotope records from two widely separated sites support the notion that degassing of biogenic methane hydrate may have been an important factor in altering Earth's climate.

Mammalian Dispersal at the Paleocene/Eocene Boundary

Science, 2002
A profound faunal reorganization occurred near the Paleocene/Eocene boundary, when several groups of mammals abruptly appeared on the Holarctic continents. To test the hypothesis that this event featured the dispersal of groups from Asia to North America and Europe, we used isotope stratigraphy, magnetostratigraphy, and quantitative biochronology to ...

The Paleocene Primate Plesiolestes and the Origin of Microsyopidae

Folia Primatologica, 1973
Comparison of the dental morphology of the Middle Paleocene paromomyid primate Plesiolestes problematicus with that of the Early Eocene microsyopid Cynodontomystatideas indicates that Plesiolestes and Cynodontomys are closely related and that the Microsyopidae are derived from paromomyid primates.
