Otodus megalodon (/ ˈ m ɛ ɡ əl ə d ɒ n / MEG-əl-ə-don; meaning "big tooth"), commonly known as megalodon, is an extinct species of giant mackerel shark that lived approximately 23 to 3.6 million years ago (Mya), from the Early Miocene to the Early Pliocene epochs.
Still, there are some arguments that species responded differently to environmental changes, and no one factor by itself explains the large variety of extinctions. The causes may involve the interplay of climate change, competition between species, unstable population dynamics, and hunting as well as competition by humans. [15]
A new study finds that megatooth sharks’ warm-blood adaptation and giant size may have played a role in their extinction.
The Pyrenean ibex, the only animal to have been brought back from extinction and the only one to go extinct twice. Main article: De-extinction Some, such as Harvard geneticist George M. Church , believe that ongoing technological advances will let us "bring back to life" an extinct species by cloning , using DNA from the remains of that species.
Scientists don't know for sure whether the megalodon ever lived in Mississippi even if some of its teeth were found in the Magnolia State. National Megalodon Day is June 15. Here are 5 things to ...
The African bush elephant (foreground), Earth's largest extant land animal, and the Masai ostrich (background), one of Earth's largest extant birds. In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The precise definition of the term varies widely, though a common threshold is ...

The Quaternary spans from 2.58 million years ago to present day, and is the shortest geological period in the Phanerozoic Eon. It features modern animals, and dramatic changes in the climate. It is divided into two epochs: the Pleistocene and the Holocene. Megafauna of Pleistocene Europe (mammoths, cave lions, woolly rhino, reindeer, horses)
