Prehistoric Flora & Fauna
The Neogene is a geologic period and system that spans 20.45 million years from the end of the Paleogene Period 23.03 million years ago (Mya) to the beginning of the present Quaternary Period 2.58 Mya.
During the Pliocene, prehistoric life around the globe continued to adapt to the prevailing climatic cooling trend, with some notable local extinctions and disappearances.
The Oligocene epoch wasn’t especially innovative with regard to its prehistoric animals, which continued along the evolutionary paths that had been pretty much locked in during the preceding...
The Cenozoic Era is easy to define: it’s the stretch of geologic time that kicked off with the Cretaceous/Tertiary Extinction, 65...
The Eocene epoch began 10 million years after the extinction of the dinosaurs, 65 million years ago, and continued for another 22 million years, up to 34 million years ago.
It is the Earth’s most severe known extinction event, with up to 96% of all marine species and 70% of terrestrial vertebrate species becoming extinct.
The Cretaceous–Paleogene (K–Pg) extinction event, also known as the Cretaceous–Tertiary (K–T) extinction, was a mass extinction of some three-quarters of the plant and animal species on Earth that occurred over a geologically...
The Carboniferous Period lasted from about 359.2 to 299 million years ago during the late Paleozoic Era.
The Snowball Earth hypothesis proposes that Earth’s surface became entirely or nearly entirely frozen at least once, sometime earlier than 650 Mya (million years ago).
