WebPaleocene Epoch, also spelled Palaeocene 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.
WebDec 15, 2006 · Abstract. The Paleocene-Eocene Thermal Maximum (PETM, ∼55 million years ago) was an interval of global warming and ocean acidification attributed to rapid release and oxidation of buried carbon. We show that the onset of the PETM coincided with a prominent increase in the origination and extinction of calcareous phytoplankton. WebOct 1, 2024 · We also investigated speciation and extinction rates separately for each geological era (Late Cretaceous, Paleocene, Eocene, Oligocene, Miocene, Pliocene, and Pleistocene) (SI Appendix, Fig. S6). To investigate how the evolution of the temperature niche–trait drove patterns of speciation and extinction across lineages, we looked at the ...
