A species of extinct shark that lived during the Miocene and Pliocene epochs. The species' scientific name is Carcharocles megalodon, although a few scientists argue the genus Otodus is more accurate. A giant Megalodon tooth with great white shark teeth
Of or pertaining to the epoch, or the deposits, following the Tertiary, and immediately preceding man.
Megalodon (Otodus megalodon), meaning , is an extinct species of mackerel shark that lived approximately 23 to 3.6 million years ago (mya), during the Early Miocene to the Pliocene. It was formerly thought to be a member of the family Lamnidae and a close relative of the great white shark (Carcharodon carcharias).
from two million to 11 thousand years ago; extensive glaciation of the northern hemisphere; the time of human evolution
relating to or denoting the first epoch of the Quaternary period, between the Pliocene and Holocene epochs.
the Pleistocene epoch or the system of deposits laid down during it.
The Pleistocene ( PLYSE-tə-seen, -toh-, often referred to as the Ice Age) is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the world's most recent period of repeated glaciations. Before a change finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP).
