Qué (quién) es Paleocene$57318$ - definición

SECOND AGE OF THE PALEOCENE EPOCH
Middle Paleocene; Selandian age
  • The [[GSSP]] marking the lower boundary of the Selandian at Itzurun, Spain

Paleocene–Eocene Thermal Maximum         
  • Climate change during the last 65 million years as expressed by the oxygen isotope composition of benthic foraminifera. The Paleocene-Eocene thermal maximum (PETM) is characterized by a brief but prominent excursion, attributed to rapid warming. Note that the excursion is understated in this graph due to the smoothing of data.
  • ''[[Azolla]]'' floating ferns, fossils of this genus indicate [[subtropic]]al weather at the North Pole
  • A stacked record of temperatures and ice volume in the deep ocean through the Mesozoic and Cenozoic periods.<br />LPTM— Paleocene-Eocene thermal maximum<br />OAEs— oceanic anoxic events<br />MME— mid-Maastrichtian event
RAPID (IN GEOLOGICAL TERMS) GLOBAL WARMING, PROFOUND CHANGES IN ECOSYSTEMS, AND MAJOR PERTURBATIONS IN THE CARBON CYCLE WHICH STARTED ABOUT 55.0 MILLION YEARS AGO
Paleocene-Eocene thermal maximum; Palaeocene-Eocene Thermal Maximum; Paleocene-Eocene warming; Petm; Palaeocene-Eocene Temperature Maximum; PETM; Paleocene-Eocene Thermal Maximum; Palaeocene–Eocene Thermal Maximum; Paleocene eocene thermal maximum; Paleocene–Eocene thermal maximum; Initial Eocene Thermal Maximum; EECO
The Paleocene–Eocene thermal maximum (PETM), alternatively (ETM1), and formerly known as the "Initial Eocene" or "", was a time period with a more than 5–8 °C global average temperature rise across the event. This climate event occurred at the time boundary of the Paleocene and Eocene geological epochs.

Selandian

The Selandian is a stage in the Paleocene. It spans the time between 61.6 and 59.2 Ma. It is preceded by the Danian and followed by the Thanetian. Sometimes the Paleocene is subdivided in subepochs, in which the Selandian forms the "middle Paleocene".
