The Paleocene/Eocene thermal maximum (PETM) was a time of rapid global warming in both marine and continental realms that has been attributed to a massive methane (CH4) release from marine gas hydrate reservoirs. Previously proposed mechanisms for this methane release rely on a change in deepwater source region(s) to increase water temperatures rapidly enough to trigger the massive thermal diss...

[1] Study of bulk nitrogen contents and isotopic composition in Arctic Ocean sequences (Integrated Ocean Drilling Program Expedition 302) over the past 60 Ma revealed changes in the export flux and sources of sedimentary nitrogen. The paleoproductivity calculated from the fraction of organic nitrogen to total nitrogen is distinctly lower (<20 g C m 2 a ) during the ice-covered Neogene compared ...

The article presents the results of lithological and petrophysical investigations reservoir rocks Eocene-Paleocene Formations, which is one main hydrocarbon prolific horizons in Central Eastern Ciscaucasia. These include characteristics pore space parameters for these stratigraphic intervals.

Sandownids are a group of Early Cretaceous-Paleocene turtles that for several decades have been only known by cranial and very fragmentary postcranial elements. Here I report and describe the most complete sandownid turtle known so far, including articulated skull, lower jaw and postcranial elements, from the Early Cretaceous (upper Barremian-lower Aptian, >120 Ma), Paja Formation, Villa de Ley...

A large collection of dentigerous jaws quarried from the Gao Mine locality, late Paleocene, Paskapoo Formation, central Alberta, Canada, documents a new species early Paleogene phenacodontid “condylarth” Ectocion Cope, 1882. The species, stockeyae, smallest genus, occurs well before abrupt global warming at Paleocene–Eocene Thermal Maximum, an event purportedly causing rapid evolution “dwarfed”...

[1] The late Paleocene to the early Eocene ( 58–52 Ma) was marked by significant changes in global climate and carbon cycling. The evidence for these changes includes stable isotope records that reveal prominent decreases in ı18O and ı13C, suggesting a rise in Earth’s surface temperature ( 4ıC) and a drop in net carbon output from the ocean and atmosphere. Concurrently, deep-sea carbonate recor...
