The Pliocene Epoch is the epoch in the geologic timescale that extends from 5.333 million to 2.58 million years BP. It is the second and most recent epoch of the Neogene Period in the Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. What is Pl...
How long is the period of an average long-period comet? Why is there no universal time? What factors does the period of a pendulum depend upon? What is current? During the pre-industrial era, what were the carbon dioxide levels like?
The most recent ~66 million years of Earth’s history (the Cenozoic Era) exhibits a rich succession of tectonic, climatic, carbon cycling, and ecological states, summarized in Fig.1. We focus on two broad periods; the early Eocene, which provides an example of extreme (for the Cenozoic) ...
The Silurian period occurred a) during the Hadean eon. b) after the Permian era. c) during the Mesozoic era. d) before the Neogene period. What is the age of the oldest eukaryotic fossils? The Cambrian geological period is characterized by the first major extinction event of complex organism...
The beginning of the Quaternary Period is formally tied to 2.58 Ma, the age of the GSSP for the Gelasian Stage in the Monte San Nicola section in Italy, corresponding to the Gauss-Matuyama paleomagnetic reversal [1,2]. Around 2.7–2.6 Ma, the glacial activity of the Northern Hemisphere inc...
