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.
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 ...
Fossil finds of ichthyosaur embryos showed that at least one group of marine reptiles had borne live young. The first to claim that similar embryos had been found in plesiosaurs was Harry Govier Seeley , who reported in 1887 having acquired a nodule with four to eight tiny skeletons. [ 126 ]

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 ...
Plesiosaurus (Greek: πλησίος (plesios), near to + σαῦρος (sauros), lizard) is a genus of extinct, large marine sauropterygian reptile that lived during the Early Jurassic. It is known by nearly complete skeletons from the Lias of England. It is distinguishable by its small head, long and slender neck, broad turtle-like body, a ...
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]
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 ...
