    Between and the CGS mapped and published open-file reports covering twenty preliminary minute quadrangles in the area between Colorado Springs and Denver. Most of these quadrangles contain exposures of Upper Cretaceous through Eocene strata deposited as synorogenic sedimentary units that filled the Laramide Denver Basin. This report unifies and .   The biostratigraphic subdivision of the reference sections using diatoms and dinocysts is discussed. The recently recognized stratigraphic units, Smyshlyaevka and Karanino within the Kamyshin (Upper Paleocene) and Proleyka (Lower Eocene) regional stages are Author: T. V. Oreshkina, G. N. Aleksandrova.

    Gastornis, formerly known as Diatryma, is an extinct genus of large flightless birds. They lived in the late Paleocene and early Eocene epochs of the first remains were discovered in the midth century. In the s, the famous American paleontologist Edward Drinker Cope discovered another, more complete set of fossils in North America, and named them : Aves. The Upper Cretaceous is the last geological epoch in the began million years ago, and ended 66 million years ago.. The Cretaceous is traditionally divided into Lower Cretaceous (early), and Upper Cretaceous (late), because of the different rocks reflect the conditions in which they were formed. From lowest to highest, it is subdivided into the Mesozoic era (– mya): Cretaceous .

    Paleocene - Eocene Stratigraphy and Paleontology of East-Central Texas: Wilcox Group - Claiborne Group - Jackson Group Strata SUMMARY The 4 locations we will visit today provide an opportunity to examine and discuss depositional environments and stratigraphic relationships in parts of the Wilcox Group, Claiborne and Jackson groups as developed. On the basis of palynological and geochemical records, upper Paleocene to lower Eocene sediments from Expedition Hole MA can generally be divided in two major intervals, that is, upper Paleocene through lower lower Eocene (Cores 35X–27X, at ∼– mcd) and upper lower Eocene (Cores 24X–12X, at ∼– mcd).Cited by:

The Wilcox Formation (upper Paleocene–lower Eocene) is a world-class hydrocarbon resource in the Gulf of Mexico.

Since the late ’s, the onshore Wilcox trend has produced primarily gas from fluvial, deltaic, and shallow marine sandstone reservoirs from southwest Louisiana to south Texas and northeast Mexico.

Therefore, the vertebrae from the Lower Eocene and Upper Paleocene localities apparently belong to the Estes, R., Sauria terrestria, Amphisbaenia. Handbuch.

An epicontinental sea bisected West Africa periodically from the Late Cretaceous to the early Eocene, in dramatic contrast to the current Sahara Desert that dominates the same region today.

A detailed stratigraphic study of over m of Upper Cretaceous through lower Eocene sedimentary rocks in the Wind River basin. Wyoming, has refined and expanded previous work and conclusions. A much larger data base than previously available was assembled to include a correlation net of Analysis of lithofacies, paleoflow directions, and sandstone petrography of upper Paleocene-lower Eocene paralic and continental sediments exposed along the transpressional suture zone of the western margin of the Indian plate indicate that the process of deformation and uplift of the carbonate shelf in this area had started by late Paleocene time.

Paleocene Epoch, first major worldwide division of rocks and time of the Paleogene Period, spanning the interval between 66 million and 56 million years ago. The Paleocene Epoch was preceded by the Cretaceous Period and was followed by the Eocene Epoch. The Paleocene is subdivided into three ages.

The Paleocene/Eocene boundary is situated in the lower part of polarity chron C24r, but its precise position and age have been contentious. Dates range from about (Berg-gren et al., b) to million years ago (Gradstein et al., ) in various reports over the past decade or so, most centering around million years ago.
