Eocene Epoch | Climate, Flora Fauna | Britannica Eocene Epoch, second of three major worldwide divisions of the Paleogene Period (66 million to 23 million years ago) that began 56 million years ago and ended 33 9 million years ago It follows the Paleocene Epoch and precedes the Oligocene Epoch
The Eocene Epoch - University of California Museum of . . . The early Eocene (Ypresian) is thought to have had the highest mean annual temperatures of the entire Cenozoic Era, with temperatures about 30° C; relatively low temperature gradients from pole to pole; and high precipitation in a world that was essentially ice-free
Eocene - New World Encyclopedia The Eocene epoch (56-34 million years ago) is a major division of the geologic timescale and the second epoch of the Palaeogene period in the Cenozoic era The Eocene spans the time from the end of the Paleocene epoch to the beginning of the Oligocene epoch
Evolution: Change: Deep Time - PBS Early in the Eocene, the global climate remains warm As the continents move ever closer to their present-day positions, this plate activity alters ocean and air circulation patterns By the end
Eocene Epoch (56 – 34 million years ago) – First primates . . . It is the second epoch of the Paleogene Period, following the Palaeocene and preceding the Oligocene The Eocene is characterised by significant climatic shifts, the diversification of mammals, and the emergence of many modern groups of plants and animals
Eocene Epoch in Geological Time Scale in Archaeology . . . The Eocene was an epoch of significant mammalian evolution, following the extinction of dinosaurs at the end of the Cretaceous period A wide range of mammalian families emerged during this time, many of which still exist today

Eocene–Oligocene extinction event - Wikipedia The Eocene–Oligocene extinction event, also called the Eocene-Oligocene transition (EOT) or Grande Coupure (French for "great cut"), is the transition between the end of the Eocene and the beginning of the Oligocene, an extinction event and faunal turnover occurring between 33 9 and 33 4 million years ago [1]
