Climate lessons from the last global warming

The Earth experienced one of the largest and most rapid climate warming events in its history 56 million years ago: the Paleocene-Eocene Thermal Maximum (PETM), which has similarities to current and future warming. This episode ...

Largest flower preserved in amber from over 33 million years ago

New images of the largest-known fossilized flower to be preserved in amber—which at 28 millimeters across is nearly three times the size of other preserved flowers—are published in the journal Scientific Reports.

The Eocene (symbol EO) Epoch, lasting from about 56 to 34 million years ago (55.8±0.2 to 33.9±0.1 Ma), is a major division of the geologic timescale and the second epoch of the Paleogene Period in the Cenozoic Era. The Eocene spans the time from the end of the Palaeocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by the emergence of the first modern mammals. The end is set at a major extinction event called Grande Coupure (the "Great Break" in continuity), which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the epoch are well identified, though their exact dates are slightly uncertain.

The name Eocene comes from the Greek ἠώς (eos, dawn) and καινός (kainos, new) and refers to the "dawn" of modern ('new') mammalian fauna that appeared during the epoch.
