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.
Megalodon is an extinct genus of bivalve molluscs that reportedly lived from the Devonian to the Jurassic period. [1] It is not clear, however, that all the fossils assigned to Megalodon from that span of time really belong in the same genus. Jurassic relatives of Megalodon such as Pachyrisma grande were closely related to the rudists. [2]
Marine mammals likely constituted a big part of megalodon's menu, so with it gone, they were free to thrive. Observations indicate that in the years since the mega-shark's extinction, baleen ...
A giant shark that was known as a megalodon use to terrorize the underwater world. Although the enormous sharks didn't make the evolutionary cut, researchers believe they still had a big impact on ...
One of the most striking fossils around today are the teeth and reconstructed jaws of the megalodon.The jaws of the extinct shark are so big, one or two people can stand inside them. They're ...
Livyatan is an extinct genus of macroraptorial sperm whale containing one known species: L. melvillei. The genus name was inspired by the biblical sea monster Leviathan, and the species name by Herman Melville, the author of the famous novel Moby-Dick about a white bull sperm whale. Herman Melville often referred to whales as "Leviathans" in ...

During the Late Pleistocene, particularly from around 50,000 years ago onwards, most large mammal species became extinct, including 80% of all mammals greater than 1,000 kilograms (2,200 lb), while small animals were largely unaffected. This pronouncedly size-biased extinction is otherwise unprecedented in the geological record.
