Megalodon size estimates vary depending on the method used, with maximum total length estimates ranging from 14.2–20.3 meters (47–67 ft). [ 35 ] [ 40 ] [ 25 ] A 2015 study estimated the modal total body length at 10.5 meters (34 ft), calculated from 544 megalodon teeth, found throughout geological time and geography, including juveniles and ...
The maximum size of the whale shark is uncertain. Various reports suggest individuals around 18 metres (59 ft), but many of these reports lack detailed measurements and documentation. McClain et al. (2015) consider this whale shark as the largest reliably measured. [9] Meekan et al. (2020) studied whale sharks over a 10-year period.
A largest verified specimen is 12.65 m [2], however, several specimens over 18 m in length have been reported. [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).

“And it represents an entire ecology of the ocean 9 millions of years ago.” The fossils were first uncovered during the school’s modernization project, which began in 2022.
Most estimates of megalodon's size extrapolate from teeth, with maximum length estimates up to 10–20.3 meters (33–67 ft) [2] [3] [5] and average length estimates of 10.5 meters (34 ft). [ 6 ] [ 7 ] Due to fragmentary remains, there have been many contradictory size estimates for megalodon, as they can only be drawn from fossil teeth and ...

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 ...
