LATE EOCENE Meaning and
Definition
-
Late Eocene refers to a distinct epoch in the geological timescale that occurred approximately between 37 to 33.9 million years ago, towards the end of the Eocene period. It is a subdivision of the larger Eocene epoch, which is part of the Paleogene period within the Cenozoic era. During the Late Eocene, significant geological and biological events took place, shaping and transforming the Earth's environment and life forms.
Geologically, this period was characterized by a warm climate, as the Earth was experiencing a greenhouse phase with high levels of carbon dioxide in the atmosphere. The Late Eocene witnessed the continued uplift of mountain ranges, such as the Himalayas, resulting from tectonic activity. This uplift led to changes in land and sea configurations, affecting the patterns of ocean currents and global climate systems.
Biologically, the Late Eocene was a time of transition and evolution. Many new plant and animal species arose, adapting to the changing environment. Mammals thrived and diversified, with herbivores like early horses and rhinoceroses undergoing significant evolution. Additionally, the marine ecosystem saw the emergence of unique and diverse marine mammals, including early whales.
Overall, the Late Eocene represents a crucial period in Earth's history, characterized by the dynamic interplay of geologic and biological transformations that shaped the planet's landscape and life forms. The study of this era provides valuable insights into the Earth's past climate, geological processes, and the evolution of various organisms.
Etymology of LATE EOCENE
The word "late Eocene" is a scientific term used in the field of geology and paleontology to refer to a specific time period in Earth's history.
Etymologically, the word "late" comes from the Old English word "lǣt" which means slow or tardy. It has been used in English since the 14th century to indicate the end or final phase of something. In the context of geologic time periods, "late" refers to the later part of a particular epoch or era.
The term "Eocene" refers to a division of the geologic timescale. It is derived from the Greek words "eos" meaning dawn, and "kainos" meaning new. The term was first introduced by the Scottish geologist Charles Lyell in 1833.
