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.

Size comparison between a human and two species of Basilosaurus, B. cetiodes (dark blue) and B. isis The heaviest archeocete , and possibly the heaviest known mammal was Perucetus , with weight estimated at 85–340 t (84–335 long tons; 94–375 short tons), while length is estimated at 17.0–20.1 meters (55.8–65.9 ft), [ 108 ] possibly ...
Helicoprion is a genus of extinct shark-like [1] eugeneodont fish. Almost all fossil specimens are of spirally arranged clusters of the individuals' teeth, called "tooth whorls", which in life were embedded in the lower jaw.
