1. eocene

   Eocene is a geological epoch that lasted from about 56 to 33.9 million years ago. It is the second epoch of the Paleogene period in the modern Cenozoic era, coming after the Paleocene epoch and before the Oligocene epoch. The Eocene is often characterized by the emergence of modern flora and a relatively warm global climate. During this epoch, many new types of mammals evolved, and Earth's surface changed dramatically with the movement of continents.

1. Eocene

   The Eocene epoch, lasting from 56 to 33.9 million years ago, 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 a brief period in which the concentration of the carbon isotope ¹³C in the atmosphere was exceptionally low in comparison with the more common isotope ¹²C. The end is set at a major extinction event called the Grande Coupure or the Eocene–Oligocene extinction event, 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 and καινός and refers to the "dawn" of modern fauna that appeared during the epoch.
