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.
)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. ) to a human Homo sapiens (180 cm). C. megalodon is only known from teeth and vertebrae, the silhouette shown here is speculative.
Meg 2: The Trench hits theaters this week with a larger-than-life depiction of the megalodon. Here’s what we actually know about the beast, according to scientists.

The species vanished about 3.6 million years ago, experts say. Still, a research team recently spotted something that looked amazingly like a megalodon while using a fish finder off the New ...
Comparative studies of the centrum radii and growth rings on the vertebrae of O. obliquus and the extant great white shark through X-rays have concluded that the sizes of the vertebrae at birth are similar, meaning that the offspring of both species would have the same size (between 1.1 and 1.6 m (3.6 and 5.2 ft) in length); they also revealed ...
