Chronostratigraphic terminology at the Paleocene/Eocene boundary

open access: yes, 2003
Integrated research over the past decade has led to the recognition of a short (150-200 k.y.) interval of Paleogene time within Chron C24r at ~55.5 Ma, formerly termed the late Paleocene Thermal Maximum (LPTM) but more recently the Paleocene-Eocene Thermal Maximum (PETM), that was crucial in the climatic, paleoceanographic, and biotic evolution of our ...

Patterns of megafloral change across the Cretaceous-Tertiary boundary in the Northern Great Plains and Rocky Mountains [PDF]

open access: yes
The spatial and temporal distribution of vegetation in the terminal Cretaceous of Western Interior North America was a complex mosaic resulting from the interaction of factors including a shifting coastline, tectonic activity, a mild, possibly ...

Reconstruction of a latest Paleocene shallow-marine eutrophic paleoenvironment at Sidi Nasseur (Central Tunisia) based on foraminifera, ostracoda, calcareous nannofossils and stable isotopes (d13C, d18O)

open access: yesGeologica Acta, 2009
In order to unravel faunal and paleoenvironmental parameters in shallow marine settings prior to the Paleocene- Eocene thermal maximum, we investigated the Sidi Nasseur section (NAS) in Central Tunisia.

WIDER PALEOGEOGRAPHICAL DISTRIBUTION OF BOTHREMYDID TURTLES IN NORTHERN SOUTH AMERICA DURING THE PALEOCENE–EOCENE

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina
Bothremydidae was one of the most diverse and widespread group of side-necked turtles (pleurodirans) during the Cretaceous and part of the Paleogene. In South America, the Paleogene record of bothremydids is restricted to Puentemys mushaisaensis from ...

Recalibration of the Tethyan shallow-benthic zonation across the Paleocene-Eocene boundary: the Egyptian record

open access: yesGeologica Acta, 2009
The Galala Mountains in Egypt provide an excellent platform-basin transect with deposits spanning the Paleocene/ Eocene (P/E) boundary. These interfingering deposits enable a recalibration between platform and open marine biostratigraphic schemes.

Evaluation of existing knowledge of the tectonic history and lithospheric structure of South America [PDF]

open access: yes
While data is available on the lithospheric and crustal structure of the Andes region of South America, there is limited knowledge of these aspects of the eastern portion of the continent.
