English: A size diagram comparing various size estimates for the extinct shark Otodus megalodon to Carcharodon carcharias (great white shark), Rhincodon typus (whale shark), and a human. Also shown are megalodon specimens the estimates are based on, vertebral column IRSNB P 9893, upper anterior tooth NSM PV-19896, and lateral tooth GHC 6.
[3])and Carcharodon megalodon (Average estimated adults size about 16 - 18 m, and a largest size of 20.3 m was extrapolated from ontogenetic trends of the great white shark by Gottfried et al. 1996. [4]) to a human Homo sapiens (180 cm). C. megalodon is only known from teeth and vertebrae, the silhouette shown here is speculative.
A 2015 study linking shark size and typical swimming speed estimated that megalodon would have typically swum at 18 kilometers per hour (11 mph)–assuming that its body mass was typically 48 t (53 short tons; 47 long tons)–which is consistent with other aquatic creatures of its size, such as the fin whale (Balaenoptera physalus) which ...
A new study posits that the ancient megalodon shark was longer and slimmer than previously believed. The ancient shark has been compared to the great white, but it may have more closely resembled ...

Previous best guesses estimated that the shark's demise happened about 1.5 million years back. Now researchers are saying it took place closer to two-and-a-half million years ago.
